haze: fix duplicate-macro warnings

haze was including both `<switch.h>` and `vapours/types.hpp` which both
define `R_SUCCEEDED` and `R_FAILED`, producing compiler warnings.

The intent is that `vapours/types.hpp` only gets included when targeting
not-Switch and/or not-EL0.  But the check didn't account for
Troposphère.  Fix that.
