kselftest/arm64: Add HWCAP test for FEAT_LS64
Add tests for FEAT_LS64. Issue related instructions if feature
presents, no SIGILL should be received. When such instructions
operate on Device memory or non-cacheable memory, we may received
a SIGBUS during the test (w/o FEAT_LS64WB). Just ignore it since
we only tested whether the instruction itself can be issued as
expected on platforms declaring the support of such features.

kselftest/arm4: Provide local defines for AT_HWCAP3
Some build environments for the selftests are not picking up the newly
added AT_HWCAP3 when using the libc headers, even with headers_install
(which we require already for the arm64 selftests). As a quick fix add
local definitions of the constant to tools use it, while auxvec.h is
installed with some toolchains it needs some persuasion to get picked up.
