gtestutils: Add some explicit double casts

Browse Source 
This avoids some false positive warnings from `-Wfloat-conversion`.

The code in `gtestutils.c` is a bit odd: it uses an array of `long
double` elements, with specific indices of that array storing specific
meaningful numbers, each of which has a type which is representable as a
`long double`, but which actually isn’t.

This is a prime candidate for refactoring to not use such a type-unsafe
API where everything is marshalled through `long double`. Unfortunately,
the array is declared in `GTestLogMsg`, which is defined in the public
`gtestutils.h` header, so we can’t change it. Boo.
