[PATCH] get_maintainer: Repair STDIN usage

[Wolfram Sang <w.sang@pengutronix.de>]

Commit 22dd5b0cba50a197aaa3bd2790a29ee2e8e4e372 (fix perlcritic warnings) broke
the ability to handle STDIN because the three argument version of open() cannot
handle standard IO-streams (which is mentioned in PerlBestPractices, too).

Like checkpatch, the hints from perlcritic should be double-checked ;)
