dev-libs/userspace-rcu: add support for loong

The patch comes from https://github.com/loongarch64/userspace-rcu/pull/2
which is reviewed by the LoongArch community, but not upstreamed yet.

This has been inside loongson-overlay for a while, and is tested on real
loong hardware.

+On a ppc64 system with gcc 9.5.0 I get the following error when building

+   53 | }
+      | ^
+
+Split the inline function in 2 variants and apply the noreturn attribute
+only on the builtin_trap one.
