[V2,06/19] selftests/resctrl: Check for resctrl mount point only if resctrl FS is supported

Presently, check_resctrlfs_support() tries to open "/sys/fs/resctrl" and
will also look for resctrl mount point in "/proc/mounts" even if resctrl
file system is not supported. Both the above will fail if resctrl file
system is not supported. Hence, return immediately if resctrl file system
is not supported.
