SystemMonitor: Prefer Core::File, poll ProcessStatisticsReader correctly

Browse source 
The signature of Core::ProcessStatisticsReader::get_all changed, and
instead of requiring a pointer to an open file, it now needs a bool to
indicate whether usernames should be polled or not. `m_proc_all` was
always converted to `false` in `RefPtr::operator bool()`, so we were
missing usernames for a long time.
