We need READ_CONTROL, and actually have to ask for
the OWNER|GROUP|DACL bits if we're going to properly
check the SD.
Tested against Windows 10.

If we open a file without READ_CONTROL, requesting a security
descriptor fails with ACCESS_DENIED if any of the requested
bits OWNER|GROUP|DACL are set.
However, if we send zero as the requested bits then a
security descriptor is returned containing no data,
even though reading an SD should fail based on the
access permissions we have on the handle.
This has been tested against Windows 10, and also
passes on Samba - although in smbd we actually
read the SD off disk first, before nulling out
all the data we read. We shouldn't (we have
no rights to do so) and a subsequent commit
will fix this.
This was discovered when investigating the
smb2.winattr test, which currently relies
on exactly this behavior. It shouldn't
and the next commit will fix that.
I wanted to preserve the current smb2.winattr
behavior in a test though.

Verify a close updates the write-time for subsequent writes after an initial
write started the delayed update logic.
This covers a scenario that will become relevant with the two subsequent
commits. The next commit:
smbd: let mark_file_modified() always call trigger_write_time_update()
ensures that trigger_write_time_update() is not only called for the first write
on a file. Without that preaparatory change, the second commit:
smbd: let delayed update handler also update on-disk timestamps
alone would cause this test to fail.

This test demonstrates that Windows has a timestamp resolution of ~15ms.
When a smaller amount of time than that has passed between modifying operations
on a file, it's not necessarily detectable on a Windows 2019 server that
implements immediate timestamp updates (no delayed magic).
Note that this test relies on a low latency SMB connection. Even with a low
latency connection of eg 1m there's a chance of 1/15 that the first part of the
test expecting no timestamp change fails as the writetime is updated.
Due to this timing dependency this test is skipped in Samba CI, but it is
preserved here for future SMB2 timestamps behaviour archealogists.

ext filesystem has a time_t limit of 15032385535 (0x0x37fffffff). From
Documentation/filesystems/ext4/inodes.rst:
If the inode structure size ``sb->s_inode_size`` is larger than 128 bytes and
the ``i_inode_extra`` field is large enough to encompass the respective
``i_[cma]time_extra`` field, the ctime, atime, and mtime inode fields are
widened to 64 bits. Within this “extra” 32-bit field, the lower two bits are
used to extend the 32-bit seconds field to be 34 bit wide; the upper 30 bits
are used to provide nanosecond timestamp accuracy. Therefore, timestamps
should not overflow until May 2446. ...
Changing the test to use the value 0x37fffffff instead of 100000000000 allows
running the test locally on ext filesytems.
