[lld-macho][nfc] Expand the compact unwind symbol reloc test 

Add a bit more detail to the comments, and check that the final binary
does indeed have a `__unwind_info` section (D105557 previosly regressed
this).

Also rename the test to emphasize that we are testing relocations
compact unwind, not relocations in general.
