Simplify standard boilerplate for selected scripts

This shortens the standard boilerplate for finding and sourcing
shell function libraries for build_image, mod_image_for_test.sh and
mod_image_for_recovery.sh.

As a side effect of the change, both mod_image_for_test.sh and
mod_image_for_recovery.sh will now restart inside the chroot if
invoked from outside; this is consistent with the pre-existing
behavior of build_image.

BUG=None
TEST=run the three scripts, from both inside and outside the chroot
