busybox/mdev-mount.sh: Fix partition detect and cleanup mountpoint on fail

This fixes issues mainly seen when mounting eMMC devices:

The wildcard /sys/block/${DEVBASE}/${DEVBASE}*1 matches both "mmcblk0p1"
and "mmcblk0boot1" for example, and this results in syntax errors. Fix this
by searching for a "partition" file instead, which only exists for real
partitions and not 'fakes' like the eMMC extra's.

When mount fails, the mountpoint file is left behind, causing later attempts
at auto-mounting it to fail. If mount fails, remove the mountpoint, leaving
the system in the state as it was before the mount attempt.
