gbuild allow unitest to run once per lang in WITH_LANG_LIST

this is motivated by the new screenshot feature
the initial proposed solution involved running make screenshot once per lang
which took ~6 hours for --with-lang=ALL on tb68 a reasonnably big
windows slavebot.

with this patch, one can run make screenshot just once and get all the screenshot
the elapsed time is 36 inutes on the same box/same config a 10x improvement.
