init: factory_utils: add option 'tmpfs'
Mount tmpfs to /var/. When booting from USB disk and run factory
toolkit, writing to /var/ slows down system performance dramatically.
Since there is no need to really write to stateful partition, using
option 'tmpfs' will mount tmpfs on /var, to improve performance
(especially when running tests like touchpad, touchscreen).
Also fix the path of option_file (/mnt/stateful_partition is not linked
to /usr/local/ when the function is called).
BUG=None
TEST=cros_workon-${BOARD} chromeos-test-init; build_image test
