unlinkat: Pass flags down to the work functions
The unlinkat(2) and funlinkat(2) system calls were ignoring
AT_RESOLVE_BENEATH.
Also pass pathseg through instead of assuming it's UIO_USERSPACE.
Add some tests which make sure that AT_RESOLVE_BENEATH is handled
properly by various system calls.
Approved by: so
