uprev_firmware.sh: Fix a bug in rw_only firmware update

A recent change in firmware updater suggests that we define
'CROS_FIRMWARE_MAIN_RW_IMAGE' as an empty string early in the
firmware build.

But this script won't work well for rw_only firmware update
when the empty string of 'CROS_FIRMWARE_MAIN_RW_IMAGE'
is already defined in the ebuild.

Here is the fix.

BUG=chromium:705414
TEST=uprev_firmware -b bob -v 8785.202.0 rw_only
