selftests/rseq: check if libc rseq support is registered
When checking for libc rseq support in the library constructor, don't
only depend on the symbols presence, check that the registration was
completed.
This targets a scenario where the libc has rseq support but it is not
wired for the current architecture in 'bits/rseq.h', we want to fallback
to our internal registration mechanism.
