Don't install ssh keys via mod_for_test_scripts.

The test image ssh keys are now delivered as a separate package,
so mod_for_test_scripts/350addTestAuthKeys no longer needs to
add the keys to test images.  Additionally, this deletes support
for `build_image --nostandard_backdoor`, since that feature
depended on the 350addTestAuthKeys script.

The 350addTestAuthKeys is replaced with 350addEnvironment, in order
to preserve additional settings needed for the 'su' command to
function properly.

TEST=test ssh to a test image, test 'su' on a test image
