As found by Jeremy, VFS modules that don't provide pread_send() or
pwrite_send() hooks result in vfs_default fallback, which is
catastrophic for VFS modules with non-mounted filesystems such as
vfs_ceph.

For cephwrap_lstat, we can use ceph_statx with the AT_SYMLINK_NOFOLLOW

For setting the times via cephwrap_ntimes, We can just use ceph_setattrx

The Linux fallocate syscall offers a mode parameter which can take the
following flags:
FALLOC_FL_KEEP_SIZE
FALLOC_FL_PUNCH_HOLE (since 2.6.38)
FALLOC_FL_COLLAPSE_RANGE (since 3.15)
FALLOC_FL_ZERO_RANGE (since 3.14)
The flags are not exclusive, e.g. FALLOC_FL_PUNCH_HOLE must be specified
alongside FALLOC_FL_KEEP_SIZE.
Samba currently takes a vfs_fallocate_mode enum parameter for the VFS
fallocate hook, taking either an EXTEND_SIZE or KEEP_SIZE value. This
commit changes the fallocate hook such that it accepts a uint32_t flags
parameter, in preparation for PUNCH_HOLE and ZERO_RANGE support.
