Fix #357: allow sulogin with user different from 'root'

In issue #357 there's a proposal for optionally allowing /bin/login, but
after intense discussions we've agreed that would be opening up for all
sorts of potential (security) issues.

it's better to keep things as-is but with the added twist of supporting
a custom user at configure time, e.g., 'admin'.
