runtime: call cgocallbackg indirectly on PPC64
This is CL 312669, for PPC64.
cgocallback calls cgocallbackg after switching the stack. Call it
indirectly to bypass the linker's nosplit check. The nosplit check
fails after CL 351271, which removes ABI aliases. It would have
been failing before but the linker's nosplit check didn't resolve
ABI alias (it should) so it didn't catch that. Removing the ABI
aliases exposes it. For this partuclar case it is benign as there
is actually a stack switch in between.
Should fix PPC64 build.
