[compiler-rt][builtins][sanitizers] Update compiler-rt test cases for compatibility with system's toolchain

This patch aims to:

  • Guard ompiler-rt/test/builtins/Unit/compiler_rt_logb_test.c with macros, so

the test runs on GLIBC versions >= 2.23. This is because the test relies on
comparing its computed values to libm. Oolder versions might not compute to the
same value as the compiler-rt value.

  • Update compiler-rt/test/sanitizer_common/TestCases/Posix/getpw_getgr.cc

so that std::string is not used, since false positives may be detected.
