bazel: fix the compilation of .proto on Darwin (#63879)
On Darwin, the last argument to GCC is coming up as an empty string.
This is breaking the build of proto_library targets. However, I was not
able to reproduce with the example cpp project[0].

This commit patches the cc_wrapper of Bazel that gets installed on
Darwin to remove the last argument if it's an empty string. This is
not a probem on Linux.
