i#xxxx: Stub out rseq_is_registered_for_current_thread if HAVE_RSEQ is false.

HAVE_RSEQ allows disabling all use of the rseq syscall at compile time, except for the function `rseq_is_registered_for_current_thread` which uses rseq to infer whether rseq is in use. If HAVE_RSEQ is false, just stub out `rseq_is_registered_for_current_thread` and always return false.
