+syscall, internal/syscall/unix: Fix getrandom, clone on sparc64
+
+Since sparc is a valid architecture, the name of
+getrandom_linux_sparc.go means that it will be ignored on sparc64,
+even though it's whitelisted with a +build line.
+
+On SPARC, clone has a unique return value convention which requires
+some inline assembly to convert it to the normal convention.
