[Libguestfs] [PATCH 2/3] test-tool: add a documentation test

[Pino Toscano]

Add the podcheck.pl test, to make sure the documentation is in sync with
the available options.

Also fix the formats of options in the current POD, so it matches what
used already in other documentations, and what podcheck.pl expects.
