function drush_correct_absolute_path_for_exec

If we are going to pass a path to exec or proc_open, then we need to fix it up under CYGWIN or MINGW. In both of these environments, PHP works with absolute paths such as "C:\path". CYGWIN expects these to be converted to "/cygdrive/c/path" and MINGW expects these to be converted to "/c/path"; otherwise, the exec will not work.

This call does nothing if the parameter is not an absolute path, or we are not running under CYGWIN / MINGW.

UPDATE: It seems I was mistaken; this is only necessary if we are using cwRsync. We do not need to correct every path to exec or proc_open (thank god).
