pkgdep/git: Check kallsyms to see if QAT needs to be patched

Browse Source 
It seems that some of the kernel patches from 5.x were backported
to centos8's 4.18 kernel. This requires 0001-pci_aer.patch to be
applied on the QAT source. To determine if it's needed, check list
of exported kernel symbols to see if said patch is needed since
relying on version check is not enough in this case.
