kiwi-repart: avoid race between repart and fsck

Browse Source 
See issue #1034, this fixes non-booting CentOS-7 OEM images that fail
during repartition / FS resize.
Summary: all parted actions trigger a rescan of partition tables and
this repeatedly starts / stops systemd-fsck-root.service until it
finally fails. The workaround is to mask systemd-fsck-root.service
during repartitioning / FS resize.

# when repartitioning disks, parted and friends might trigger re-reads of

# To avoid this, disable the root fsck (is finished at this point anyway
