Allow user to disable Undo manager through MKE2FS_SCRATCH_DIR
Undo manager is a bit annoying when doing e2fsprogs testing since it
makes mke2fs significatly slower. Use the MKE2FS_SCRATCH_DIR=disable
enviroment value to disable undo manager for those of us that blow up
filesystems on a regular basis.
