perf(mining): sample system RAM at most once a second

Browse Source 
The Mining tab's memory bar read used system RAM and the wallet's own
memory on the UI thread every frame: synchronous OS queries, on Linux
an open and parse of /proc/meminfo and /proc/self/status per frame.
Both are now sampled at most once a second; the first frame after
more than a second idle resamples at once. Total RAM was already
cached and daemon RAM already comes from a background sampler.

The used-RAM and wallet-memory readings in the bar and its tooltip now
refresh at most once a second; what they show is unchanged.
