Histograms matching ScreenLocker.* are unmapped

Project Member Reported by ricea@chromium.org, Sep 2 2016

Issue description

The following histograms are present in Chromium source code but do not
appear in histograms.xml.

ScreenLocker.AuthenticationFailureTime defined at
chrome/browser/chromeos/login/lock/screen_locker.cc line 185
https://cs.chromium.org/chromium/src/chrome/browser/chromeos/login/lock/screen_locker.cc?l=185

ScreenLocker.AuthenticationSuccessTime defined at
chrome/browser/chromeos/login/lock/screen_locker.cc line 214
https://cs.chromium.org/chromium/src/chrome/browser/chromeos/login/lock/screen_locker.cc?l=214

ScreenLocker.ScreenLockTime defined at
chrome/browser/chromeos/login/lock/screen_locker.cc line 523
https://cs.chromium.org/chromium/src/chrome/browser/chromeos/login/lock/screen_locker.cc?l=523

File and line information may be out-of-date by the time you read this.

Please remove these histograms from the source code. If they were very
recently added, it may be worth adding them to histograms.xml instead, but
probably not.

This bug was automatically assigned based on git blame information. If you
are not the correct assignee for this bug, please delete the histograms
anyway.

commit 189fda007ffd7ca42913ec3edc02d10812ce495f

Add missing UMA definitions about ScreenLocker to histograms.xml

The metrics were added long time ago crrev.com/64367 without
the corresponding changes to histograms.xml. The metrics still
look interesting hence this change is to update histograms.xml.
