Force disable yjit on OpenBSD
TestRubyOptions#test_enable was broken on OpenBSD after the yjit merge. --yjit (and --enable-all, which enables --yjit) fails on OpenBSD because yjit uses an insecure mmap call (both writable and executable), in alloc_exec_mem, which OpenBSD does not allow. This can probably be reverted if yjit switches to a more secure mmap design (writable xor executable). This would involve initially calling mmap with PROT_READ | PROT_WRITE, and after writing of executable code has finished, using mprotect to switch to PROT_READ | PROT_EXEC. I believe Firefox uses this approach for their Javascript engine since Firefox 46.
