Enable the RSEQ test for RISC-V, which according to HAVE_RSEQ is supported
by the kernel and thus should be tested.  The RSEQ test was added shortly
before RISC-V selftests support landed, i.e. was likely overlooked during
merging.

Note, the RSEQ test currently doesn't compile with clang due to an issue
in the base RSEQ test code.  Given that clang is constantly broken for KVM
selftests, enable the RSEQ test and deal with its broken clang state in a
separate commit/series.
