[NET_SCHED]: Export real timer resolution in /proc/net/psched
The timer resolution exported in /proc/net/psched is used by userspace to calculate HTB's burst values. Currently it is set to HZ, since we're now using hrtimers, use KTIME_MONOTONIC_RES, which makes HTB use smaller burst values. This patch also affects libnl, which incorrectly uses this value for the SFQ perturbation parameter, which is always in seconds, and some routing cache values, which are in USER_HZ, so both cases are broken anyway.
