libpcsxcore: Set unsafe flags after reset

Lightrec is only initialized once, when the emulator starts. We need to
set the unsafe flags after reset because the setting will be different
across games.

Funnily enough, emulating the CPU less accurately by only invalidating

These hacks will also make Lightrec generate faster code, but they are
