tests/functional: Add test for MPIPL in PowerNV

With MPIPL support implemented, enable fadump's functional test for PowerNV

Also, current functional test for powernv uses op-build's Linux 5.10 image,
which doesn't support adding "fadump=on" in argument due to this:

    Kernel is locked down from Kernel configuration; see man kernel_lockdown.7

Hence, instead of op-build's image, use the newer fedora vmlinuz as used
in FADump PSeries functional test

Also due to "bash#" string not showing up, rely on sh: no job control to
check if testcase has reached till shell
