mesa: use C locale for _mesa_strtod()
_mesa_strtod() is used for shader/program parsing where the decimal point character is always '.' Use strtod_l() with a "C" locale to ensure correct string->double conversion when the actual locale uses another character such as ',' for the decimal point. Fixes bug 24531.
