Some metrics are missing the '/sec' suffix. This fix first tries to add

the counter without the '/sec' and if fails, try again with it. If the
second call fails, throw an exception.This issue must be addressed at the
java level (and not C code), since the counter names must be translated
before to support i18n native OS locals.
Please also note, the C code (at Pdh.c), tries to do the same, but at
this level we cannot use the translation mechanism the Java level offers,
hence this fix won't handle non-English i18n locals.
