utils: Convert smbtree to use libsmbclient

We have the domain browsing functionality in libsmbclient, don't
duplicate it in smbtree with special code. Not too much gain in lines
of code, but the new code is much more regular and reuses
functionality provided elsewhere.

This removes the "-b" option from smbtree, libsmbclient always does
that.
