fng-install: fix postinstall-status file path
The status file cannot be found when processing do_installation(): cat: can't open '/mnt/target/var/volatile//tmp/yocto-postinstall-status': No such file or directory
This happends because:
- target rootfs is not mounted at that moment
- ${ABSTARGETTMP}/tmp is not persistant (all files will be removed after umount).
Switch back to /tmp as it's shared between fngsystem and target rootfs (mount -o bind /tmp $TARGETROOT/tmp).
