Fix CPU processor use reporting on Mono.
Despite the comments in the code, it appears that the issue where the .NET performance counter was wrongly idle time time on Mono was fixed in 2009. https://bugzilla.novell.com/show_bug.cgi?id=468625 Which means that the workaround is no longer necessary and produces bad results instead.
