debug(core): make C impl of __fatal_error print to stderr

Browse Source 
Previously, any C assertion or other case of __fatal_error would only
show the RSOD, but not print to emulator output.

That is (a) mildly annoying, and (b) would not work in the weird case in
Rust unit tests where graphics are not available.
