get_maintainer: don't remind about no git repo when --nogit is used

When --nogit is used with scripts/get_maintainer.pl, the script spews 4
lines of unnecessary information (noise).  Do not print those lines when
--nogit is specified.

This change removes the printing of these 4 lines:

  ./scripts/get_maintainer.pl: No supported VCS found.  Add --nogit to options?
  Using a git repository produces better results.
