passdb: Allow a passdb module to do idmap for everything

This patch seems odd, but the pdb_samba_dsdb module has exactly this
semantics.  That is, the pdb_samba_dsdb is responsible for all IDMAP
values, due to backing on to the idmap.ldb allocator.  This option is
added so we can continue to support the mappings written into that
database even when switching winbindd implementations - the source4/
winbind code would only ask the idmap_ldb code, no matter what the
SID.

Almost all of the behaviour for this is already in winbindd, but we
need this extra flag function so as to avoid (currently intentional)
errors at startup due to not having a per-domain allocation
configured in the smb.conf.

s3-winbindd: Honour pdb_is_responsible_for_everything_else()

This allows us to avoid running idmap_init_default_domain() which
gives an error in the default AD DC config.
