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).
