Kir Kolyshkin edeb3b376c libct/intelrdt: faster init if rdt is unsupported

In a (quite common) case RDT is not supported by the kernel/hardware,
it does not make sense to parse /proc/cpuinfo and /proc/self/mountinfo,
and yet the current code does it (on every runc exec, for example).

Fortunately, there is a quick way to check whether RDT is available --
if so, kernel creates /sys/fs/resctrl directory. Check its existence,
and skip all the other initialization if it's not present.
