Fix the build job on macos-latest.

After commit a022cc0 removed the `-std` flag from Makefile (and re2.pc),
this job started failing on macos-latest. I'm guessing that "AppleClang"
is staying with `-ansi` (i.e. `-std=c89` or `-std=c++98`) as the default
whereas upstream Clang changes the default over time much like GCC does.
Thus, set the `-std` flag explicitly just to get this job passing again.
(The other two flags are the default provided for CXXFLAGS in Makefile.)
