[Telemetry] Reduce size of browser info logs
[Telemetry] Reduce size of browser info logs

1. Do not output the browser commandline. This is already output elsewhere.
2. Instead of something like this:

(INFO) 2019-03-19 10:52:50,268 browser._LogBrowserInfo:97  Browser started (pid=28361).
(INFO) 2019-03-19 10:52:50,269 browser._LogBrowserInfo:100  OS: android M
(INFO) 2019-03-19 10:52:50,322 browser._LogBrowserInfo:107  Model: AOSP on Shamu

We output something like this:

(INFO) 2019-03-19 15:59:29,184 browser._LogBrowserInfo:128  Browser information:
Browser started (pid=115877).
