Bug 12844: Force the symbol place in the tests

Bug 12844: Force the symbol place in the tests

Looking with Katrin at the default configuration of Number::Format, she
has the p_cs_precedes value set to 0 (put the symbol at the end) and
p_sep_by_sep set to 1.

Now it is possible to sent these values to the format subroutine.
On this way, the tests can force them in order to pass on all configuration.

This default value for this variable certainly depends on the locales.
