JUN JIE NAN 6b7cf26689 Fixed device or resource busy issue in EXIT trap ...

cleanup for ramdisk failed to umount TMP_BUILD_DIR with device or
resource busy error.

The patch unmounts all the mountpoints under TMP_BUILD_DIR and
detaches loop devices associated with TMP_IMAGE_PATH.

The unmounts are applied with both force(-f) and lazy(-l)
options. Force option is only for NFS mounts, it's kept here since no
harm for lazy option.
