rGc4a6d3b183af: capsicum-test: Update for O_BENEATH removal
rG8cf5812af4b7: capsicum-test: Update for O_BENEATH removal
Summary

Update the tests to check O_RESOLVE_BENEATH instead.
If this looks reasonable, I'll try to upstream this change.
This keeps a compat fallback for O_BENEATH since the Linux port still
has/had O_BENEATH with "no .., no absolute paths" semantics.

Test Plan

/usr/tests/sys/capsicum/capsicum-test -u 977 passes and runs the O_RESOLVE_BENEATH tests.

This is weird, because if you redefine O_RESOLVE_BENEATH as O_BENEATH, this could succeed (depending on the cwd).

I think there could be other interesting errors if cwd == /. I guess the testsuite should check that the cwd is not inside / or /etc.
