Auto merge of #60402 - michaelwoerister:update-profiler-rt-build, r=alexcrichton
libprofiler_builtins: Set compilation flags more correctly for C code.

In particular, set `COMPILER_RT_HAS_FCNTL_LCK` and `COMPILER_RT_HAS_ATOMICS` as appropriate. This should get rid of the various runtime warnings when executing instrumented binaries.

The build script is using a heuristic here that hopefully is sufficient for the time being.

r? @alexcrichton

Fixes #59531.
