mod_image_for_recovery.sh: some cleanup.

Browse Source 
Motivated by the need to share the default recovery image name across
scripts (image_to_usb.sh in this case) and have it setup in common.sh.
Includes some general cleanup steps such flags and usage strings,
migrating function definitions to the beginning of the script, etc.

BUG=chromium-os:26010
TEST=Tested mod_image_for_recovery.sh on local host.
