kselftest/arm64: add lse and lse2 features to hwcap test

Browse source

Add the LSE and various features check in the set of hwcap tests.

As stated in the ARM manual, the LSE2 feature allows for atomic access
to unaligned memory. Therefore, for processors that only have the LSE
feature, we register .sigbus_fn to test their ability to perform
unaligned access.
