In installperl, record the state of options in %opts instead of lexicals.

Replace all lexicals used to track the state of command line options with
entries in the hash %opts. Make an exception for $versiononly, as it is
controlled by 2 different command line options, and accessed in significantly
more places than the state of any other command line option.
