Subject: [PATCH 0/2] kselftest/arm64: Improvements to BTI tests on non-BTI systems

While looking at the BTI selftest results on a non-BTI system I noticed
that not only are we printing invalid test numbers in that case, we're
skipping running the tests entirely even though there's a well defined
ABI we could be verifying and the code already knows what the results
should be.

The first patch here is a fix to the reporting of test numbers when
skipping, the second one just removes the skipping entirely in favour of
a runtime check for what the result of a BTI binary should be.
