checklayer: check layer in BBLAYERS before test

layer under test should absent from BBLAYERS when running
yocto-check-layer. This allow to get signatures before layer
under test. There are existing steps to add the layer under
test to BBLAYERS after getting initial signatures.

add steps to check for layer under test in BBLAYERS before
running any test, skip test for the layer if the layer under
test exist in BBLAYERS.
