t/porting/cpphdrcheck.t: fix cc version fallback
The `unless ($ver)` check doesn't work as intended because
`` `$cc -V 2>&1` `` captures stderr (intentionally, for Sun C). This
means with gcc or clang `$ver` ends up containing a true-ish string,
either
gcc: error: unrecognized command-line option ‘-V’
gcc: fatal error: no input files
compilation terminated.
or
clang: error: argument to '-V' is missing (expected 1 value)
clang: error: no input files
so the `$cc --version` fallback never runs.
Checking for a non-zero exit status and the word "error" in the output
seems to work reliably, though.
