runtime: improve systemstack-on-Go stack message
We reused the old C stack check mechanism for the implementation of
//go:systemstack, so when we execute a //go:systemstack function on a
user stack, the system fails by calling morestackc. However,
morestackc's message still talks about "executing C code".
Fix morestackc's message to reflect its modern usage.
