tests: nft-parsing-test: Display error reason when testing XML

Add the use of system errors (nft_parse_perror) in test_xml to know which
node is not found.

Example:
parsing xmlfiles/75-ruleset.xml: FAILED (Invalid argument)
Reason : Node "flags" not found

[ I have mangled this patch to rename this the current 'fail' message
  to 'Reason' --pablo ]
