scripts/check-syntax: Don't share global variables between processes

Instead of trying (and failing) to share a global boolean between the parent and
child subprocesses to indicate errors in a CVE, instead have check_cve() return
a bool and collect these together to report a final status.

Thanks @seth-arnold for noticing this.

scripts/check-syntax: support automatic parallelisation

Since checking of each cve is not dependant on others, use multiprocessing to
run as many in parallel as possible - when running check-syntax across of of
UCT, this results in a ~2x speedup for my local testing:

without:

real 5m43.721s
user 5m28.626s
sys 0m16.109s

with this change:

real 3m52.133s
user 25m8.199s
