[llvm-profgen][NFC] Fix test failure by making unwinder's output deterministic

Authored by wlei on Dec 7 2020, 10:02 PM.



Don't know why under Sanitizer build(asan/msan/ubsan), the std::unordered_map<string, ...>'s output order is reversed, make the regression test failed.

This change creates a workaround by using sorted container to make the output deterministic.
