oeqa: Add allarch sstate sig test

"allarch" targets should be MACHINE invariant. This means their sstate
signature should not change regardless of which MACHINE is built.

Errors keep creeping in around this area so automating this as part
of self test seems the best way to maintain this.

The "do_build" stamps are known to differ and are harmless so those
are excluded from the test.
