runtime: use entersyscall in syscall_syscallX on Darwin

CL 197938 changed syscall* functions to call entersyscall, instead
of entersyscallblock. It missed syscall_syscallX, probably because
it was in sys_darwin_64.go, not sys_darwin.go like others. Change
that one as well.

Found during the review of CL 270380 (thanks Joel).
