cephadm/smb: Update CTDB bind mount for new socket path

Samba recently changed CTDB to derive its runtime paths from Samba's
configure options instead of using a monolithic CTDB_RUNDIR[1].
With current packaging[2], the CTDB socket path moved from
/var/run/ctdb/ctdbd.socket to /run/samba/ctdb/ctdbd.socket.

Update the CTDB runtime bind mount target from /var/run/ctdb to
/run/samba/ctdb to match the new CTDB_SOCKETDIR. Additionally,
create the CTDB pid directory, /run/ctdb, and lock directory,
/var/lib/samba/lock/ctdb, on the host side as they are hidden
when their parent directories are bind mounted over.

Ideally these directories should be created by sambacc but sambacc is
included in samba-container images that may be built with different
Samba packages where these path configurations might not hold true.
