material-arbfp: Use locale-independent double to string conversion

Browse Source 
The ARBfp programs are created with a printf() wrapper, which usually
fails in non-en locales as soon as you start throwing things like
floating point values in the mix.

We should use the g_ascii_dtostr() function which places a double into a
string buffer in a locale-independent way.
