Use LC_NUMERIC=C for tests

The following tests require dot as decimal separator:
graph1, rpn1, create-with-source-4, dcounter1, vformatter1, pdp-calc1

Set LC_NUMERIC=C, which allows these tests to pass also under locales,
where the decimal separator is not a dot by default:
de_DE, es_ES, fr_FR, nl_NL etc.
