[patch] get_maintainer: handle file names beginning with ./

[Dan Carpenter <dan.carpenter@oracle.com>]

The problem is that get_maintainer.pl doesn't work if you have a ./
prefix on the filename.  For example, if you type:

    ./scripts/get_maintainer.pl -f ./drivers/usb/usb-skeleton.c

then the current code only includes LKML and people from the git log, it
doesn't include Greg or the linux-usb list.
