The '-c x/y' option for acceptance and functional jobs now
allows to split the set of acceptance/functional tests into
chuncks just like the CI does to share resources between
multiple parallel jobs.

Adding this to runTests.sh allows to replay the exact same
list of tests that CI does. This example will execute tests
of chunk 3 from 10 chunks with mariadb and php 7.4:

Build/Scripts/runTests.sh -s functional -d mariadb -p 7.4 -c 3/10
