Bug 1418406 - Disable css-invalid/select/select-disabled-fieldset-2.html on android for perma failures. r=me, a=testonly

It appears that both select-disabled-fieldset-1 and select-disabled-fieldset-2 rely
on some other test being run first: Neither test passes if run alone, and both
tests fail with the current Android chunk divisions.
