autotest: Refactor WiFi security credentials into per type classes
This lets us be a little more abstract about the types of security
credentials we support in testing, and concentrates the relevant logic
into one place.
TEST=Passes both:
./run_remote_tests.sh --remote=chromeos1-shelf1-host3 check11b
./run_remote_tests.sh --remote=chromeos1-shelf1-host3 checkStaticWEP40
which indicates this works for both open and WEP security types.
