configure: do not fork off grep subprocess in probe_cc
grep is not required for the functionality in this instance.
This avoids an unnecessary fork, and also avoids a duplicated dumpversion call.
Furthermore, it also corrects behavior when no minor version number is present, see e.g
https://github.com/joyent/node/pull/25671.
