The intelrdt package only needs to parse mountinfo to find the mount
point of the resctrl filesystem. Users are generally going to mount the
resctrl filesystem to the pre-created /sys/fs/resctrl directory, so
there is a common case where mountinfo parsing is not required. Optimize
for the common case with a fast path which checks both for the existence
of the /sys/fs/resctrl directory and whether the resctrl filesystem was
mounted to that path using a single statfs syscall.
