get_maintainer: quiet noisy implicit -f vcs_file_exists checking

Checking command line filenames that are outside the git tree can emit a
noisy and confusing message.

Quiet that message by redirecting stderr.
Verify that the command was executed successfully.

Fixes: 4cad35a7ca ("get_maintainer.pl: reduce need for command-line option -f")
