[PULL 01/12] scripts: Detect git worktrees for get_maintainer.pl --git

[Paolo Bonzini]

From: Alexey Kardashevskiy <address@hidden>

Recent git versions support worktrees where .git is not a directory but
a file with a path to the .git repository; however the get_maintainer.pl
script only recognises the .git directory, let's fix it.
