lib: Fix samba-util dep in "errors" module
This piece of code pulls in talloc_stackframe and smb_panic into what
should be a very simple mapping library. I'm trying to reduce our
dependencies right now a bit, and I think the use cases that this fixes
(unknown NTSTATUS together with double nt_errstr() calls in the same
DEBUG) are rare enough that this is not justified.
