vmon: set locale

I'd like to get thousands markers in some of the numbers produced
via snprintf in the charts, so call setlocale() with "" so it
gets set to whatever the environment has.

e.g.
LC_ALL=$LANG src/vmon

In Arch here gets my LC_ALL set to "en_US.UTF-8", which will put
commas in for thousands separators wherever the format modifier
"'" has been added.
