fsck: Allow to specify the fsck repair option in the cmdline
Some unattended systems do not have a console attached and entering the default rescue mode will not be too helpful. Allow to specify the "-y" option to attempt to fix all filesystem errors. Manually verified by downloading an image.gz of e2fsprogs, using losetup and running systemd-fsck on the loop device and varying the fsck.repair=preen|yes|no option.
