Revert of Add i18n support for Android App Restrictions. (patchset #7 id:120001 of https://codereview.chromium.org/865573002/)

Reason for revert:
Broke some GN builds, e.g.:

http://build.chromium.org/p/chromium.linux/builders/Linux%20GN/builds/24483/steps/compile/logs/stdio
http://build.chromium.org/p/chromium.chromiumos/builders/Linux%20ChromiumOS%20GN/builds/11092/steps/compile/logs/stdio

ninja: Entering directory `/mnt/data/b/build/slave/Linux_GN/build/src/out/Release'
ninja:error: expected depfile 'gen/chrome/policy_templates.d' to mention 'gen/chrome/app/policy/common/html/am/chrome_policy_list.html', got 'gen/chrome/app/policy/linux/examples/chrome.json'
