Prepare-overlay service: check for mountpoint before removing workdir

The service was getting called twice, resulting in a removal of the
overlayfs workdir while the overlay was mounted. Solve this by checking
if the /etc overlay is mounted yet before removing the workdir. Need to
add mountpoint to busybox for this.

Resolves openbmc/openbmc#2429
