This fixes a regression in commit f03665bb7e8ea97699062630f2aa1bac4c5dfc7f

The use of reload_services() has a lot of side effects, e.g. reopen of
log files and other things, which are only useful in smbd, but not in rpcd_classic.
It was also unloading the user and registry shares we loaded a few lines
above.

We need to do all (re-)loading as root, otherwise we won't be able
to read root only smb.conf files, access registry shares, ...

This happens because run_proc_context_destructor() directly does a
talloc_free() on the struct proc_context's and not the enclosing
tevent_req's. run_proc_kill() makes sure that we don't follow
proc->req, but it forgets the "state->proc", which is free()'ed, but
later dereferenced in run_proc_state_destructor().

This is an attempt at a quick fix, I believe we should convert
run_proc_context->plist into an array of tevent_req's, so that we can
properly TALLOC_FREE() according to the "natural" hierarchy and not
just pull an arbitrary thread out of that heap.

906dbd0a4b CVE-2022-37966 s4:kdc: announce PA-SUPPORTED-ETYPES like windows.
We need to take the value from the msDS-SupportedEncryptionTypes
attribute and only take the default if there's no value or
if the value is 0.

For krbtgt and DC accounts we need to force support for
ARCFOUR-HMAC-MD5 and AES encryption types and add the related bits
in addtition. (Note for krbtgt msDS-SupportedEncryptionTypes is
completely ignored the hardcoded value is the default, so there's
no AES256-SK for krbtgt).

For UF_USE_DES_KEY_ONLY on the account we reset
the value to 0, these accounts are in fact disabled completely,
as they always result in KRB5KDC_ERR_ETYPE_NOSUPP.

Then we try to get all encryption keys marked in
supported_enctypes, and the available_enctypes
is a reduced set depending on what keys are
actually stored in the database.

We select the supported session key enctypes by the available
keys and in addition based on AES256-SK as well as the
"kdc force enable rc4 weak session keys" option.
