Fix debugger with GL to work with non-default locale
QApplication forces the process to use the C locale system on
"Unix/Linux" according to the docs.
The float numbers in GL shaders will be printed with printf. These will
be formatted with comma in certain locales, like LC_NUMERIC=fi_FI.UTF-8.
Force the NC_NUMERIC=C before running the QApplication.
