rGcaf9eb6e4d73: [BOLT] Fix two aarch64 tests
Summary

tls-lld test might be broken since compiler might optimize plt function
call and use address directly from got table. The test is removed since
plt-gnu-ld checks the same functionality + versioning symbol matching,
no need to keep both of the tests.
The toolchain might optimize relocations in runtime-relocs test, replace
the test compilation with yaml files.
