[PATCH libinput] meson.build: add more overrides for coverity

[Peter Hutterer]

"/usr/include/math.h", line 381: error #20: identifier "_Float32" is undefined
  # define _Mdouble_		_Float32

Same for a few others. Since we don't actually need those anyway, we can just
cast those to the some close-enough sizes. We don't have stdint.h in config.h
and meson cannot have a custom #include line in the config object. So let's go
with what does the job for now.

The extra additions are probably caused by my update to F28, but something
is wrong on the coverity side here and I'd rather #define random things 
away than not run coverity...
