[PATCH] cvsimport: update to use non-dash git commands

[Ben Walton <bwalton@artsci.utoronto.ca>]

The cvsimport module was using the old git subcommand calling
convention (eg: git-init) in several places.  Clean this up to use
only modern calling conventions and be internally consistent in how
commands are passed to system().
