[LLD][ELF] - Convert 3 testcases to use yaml instead of binaries.

[grimar]

Summary

This depends on D58779 and allows us to remove 3 binaries from inputs.

[grimar]

• Restore removed "REQUIRES X86".

[grimar]

• Remove added "REQUIRES: x86". It is not needed. Original test case also did not have it, because it uses yaml2obj and not llvm-mc.
