Until recently yaml2obj didn't properly support relocations for MachO.
This behavior resulted in binaries having invalid relocations.
In this diff we adjust the existing tests as follows:
for the tests which don't actually look at any relocations they are removed,
for the tests which essentially depend on relocations they are fixed.
Test plan: make check-all

Imagine we have the following invocation:
`FileCheck -check-prefix=UNKNOWN-PREFIX -implicit-check-not=something`
When the check prefix does not exist it does not fail.
This patch fixes the issue.
