KVM: selftests: Replace "paddr" with "gpa" throughout

Replace all variations of "paddr" variables in KVM selftests with "gpa",
with the exception of the ELF structures, as those fields are not specific
to guest virtual addresses, to complete the conversion from vm_paddr_t to
gpa_t.

No functional change intended.
