Various startup metrics (e.g. Startup.BrowserMessageLoopStartTimeMainEntry) have weird "< 7 minutes system startup" logic

Project Member Reported by asvitk...@chromium.org, Aug 4 2016

Issue description

Various startup metrics (e.g. Startup.BrowserMessageLoopStartTimeMainEntry) have weird "< 7 minutes system startup" logic.

This makes them hard to compare to other metrics that _don't_ have this logic.

Suggestion: Remove this bit of logic so that the startup metrics are made consistent.

fdoray@, would you mind doing this clean up? Thanks!

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/0a804c57f2814605540ef11db5187fb94cf359d8

commit 0a804c57f2814605540ef11db5187fb94cf359d8
Author: fdoray <fdoray@chromium.org>

Remove "< 7 minutes system startup" from startup metrics.

Record these histograms all the time instead of only after 7 minutes
of OS uptime:
- Startup.LoadTime.ExeMainToDllMain
- Startup.LoadTime.ProcessCreateToDllMain
- Startup.LoadTime.ProcessCreateToExeMain
- Startup.BrowserMessageLoopStartTimeFromMainEntry
- Startup.BrowserMessageLoopStartTimeFromMainEntry.FirstRun

Note: A version of these histograms recorded after 7 minutes of OS
uptime is kept for now to allow regressions to be caught reliably.

Remove startup metrics recorded 7 minutes after system start.

Startup metrics can be sent only first 7 minutes from system start,
while expected these metrics will be sent only if 7 minutes are passed
from system start.

Since M54 hit stable, drop these metrics.
