[libc] _INCLUDE_SCUDO: check for compiler-rt in enabled RUNTIMES too

[alfredfo]

Summary

Previously including SCUDO in a libc build with runtimes/ as root was
not possible since this code only checked for compiler-rt enabled via
LLVM_ENABLED_PROJECTS.

Maybe tweak this, but I don't feel super strongly about it.
