Subject: [PATCH 12/26] virt-what.in: make option processing portable

Replace linux-specific 'getopt' usage with manual option parsing.
Because the used option are version simple (help/version) and the only
additional option is undocumented (--test-root), it's easy remove the
'getopt' usage, and make this script portable to BSD systems.
