[libvirt] [PATCH 4/5] qemufirmwaretest: Test FW path getting through qemuFirmwareGetSupported()

There is one hack hidden here, but since this is in a test, it's
okay. In order to get a list of expected firmwares in
virFirmwarePtr form I'm using virFirmwareParseList(). But
usually, in real life scenario, this function is used only to
parse a list of UEFI images which have NVRAM split out. In other
words, this function expects ${FW}:${NVRAM} pairs. But in this
test, we also want to allow just a single path: ${FW} because
some reported firmwares are just a BIOS image really. To avoid
writing some parser function, let's just pass "NULL" as ${NVRAM}
and fix the result later.
