Some locales print floating point numbers with a comma instead of a dot.
This causes problems with CSV mode because it causes extra false CSV
fields. Force the numeric locale to be always C in CSV mode.

Before:

$ LC_ALL=pl_PL.utf8  perf stat -x, true
0,399472,,task-clock,399472,100,00                      <---- extra bogus field
...

After:
$ LC_ALL=pl_PL.utf8  ./obj-perf/perf stat -x, true
0.338422,,task-clock,338422,100.00
