ulimit: remove buggy bsd implementation

The bsd implementation of ulimit produces wrong return values, so remove it
in favour of the posix implementation.

The only regression for non-Linux implementations using bsd sysdeps and not
providing an own ulimit is that the __UL_GETMAXBRK case (which is non-standard)
is left unimplemented (giving EINVAL).
