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.
