[PATCH] test-lib: introduce the '-V' short option for '--verbose-log'

["SZEDER Gábor" <szeder.dev@gmail.com>]

used test options, but due to its length it's a pain to type on the
command line.

Let's introduce the corresponding short option '-V' to save some
keystrokes.

Or it could be '-L', to emphasize the "log" part of the long option, I
don't really care.
