Remove odsign_e2e_tests_full from avf-postsubmit group

The test should match with the ART implementation in DUT.
The implementation can be built from ToT in case of trunk,
but could be a prebuilt from mainline-train-builds in case
of next.

Until we find a way to use different tests depending on
the original of the ART module in DUT, drop the test
from the avf-postsubmit group.
