Subject: [PATCH] Add sleep to workaround e2fsck errors

LP: 1960537 illustrates an issue where the calls to e2fsck in the
umount_partition call are failing due to an open file handle. At this
time, we are unable to find a root cause, and it's causing many builds
to fail for CPC. Adding a sleep 30 as a workaround as the file handle
releases within  that timeframe. This does not address root cause.
