Will Norris	7c386ca6d2	net/sockstats: fix calculation of radio power usage ... When splitting the radio monitor usage array, we were splitting at now % 3600 to get values into chronological order. This caused the value for the final second to be included at the beginning of the ordered slice rather than the end. If there was activity during that final second, an extra five seconds of high power usage would get recorded in some cases. This could result in a final calculation of greater than 100% usage. This corrects that by splitting values at (now+1 % 3600). This also simplifies the percentage calculation by always rounding values down, which is sufficient for our usage.

Mihai Parparita	782ccb5655	.github/workflows: run one set of tests with the tailscale_go build tag ... We use it to gate code that depends on custom Go toolchain, but it's currently only passed in the corp runners. Add a set on OSS so that we can catch regressions earlier. To specifically test sockstats this required adding a build tag to explicitly enable them -- they're normally on for iOS, macOS and Android only, and we don't run tests on those platforms normally.

Will Norris	75784e10e2	sockstats: add client metrics for radio power state ... power state is very roughly approximated based on observed network activity and AT&T's state transition timings for a typical 3G radio.
