sgi/acs: allow prebuilt luv-live image to be specified

Add support for a command line option to specify a absolute path of the
luv-live image to be tested with. This is useful when executing ACS tests
with a pre-built version of the luv-live ACS image. To specify the
pre-built image, use the command line option "-v" and specify the
absolute path of the luv-live image as its parameter.
