Partially fix MacOS llvm coverage collection

This allows setting GCOV on the command line to overwrite the default setting, which points to /usr/bin/gcov. In order to use this, you also need to disable the gcov coverage feature and enable the llvm coverage feature instead. The full command-line looks like this:

GCOV=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/llvm-profdata bazel coverage --features=llvm_coverage_map_format --features=-gcc_coverage_map_format //cpp:test

Progress on #10457.
