test/eal: set core mask/list config only in dedicated test

Setting a coremask was mandatory a long time ago but has been optional
for a while.
The checks on PCI whitelist/blacklist, vdev, memory rank, memory channel,
HPET, memory size and other miscs options have no requirement wrt cores.

Let's remove those coremasks so that we only care about it in the
dedicated checks.
