Skip 909 & 126 with zipapex

Tests 909 and 126 fail on zipapex due to their 'run' scripts doing
non-standard things. Add support for run-test skipping based on a
'zipapex' selector and add these tests to the skip list.

Test: ./test/testrunner.py --no-build-dependencies --runtime-zipapex <path> -t 909 -t 910
