Revert "Reland "Load QuickOffice manifest from cros rootfs""

This reverts commit 336415fa902298ba2f5e0da9d962fd61dedff5d8.

Reason for revert: suspect causing browser_tests failure on linux-chromeos-chrome

browser_tests failed because of:
All/FileTasksBrowserTest.FallbackSucceedsWithQuickOffice/Guest
All/FileTasksBrowserTest.FallbackSucceedsWithQuickOffice/Regular
All/FileTasksBrowserTest.QuickOffice/Guest
All/FileTasksBrowserTest.QuickOffice/Incognito
...6 more failure(s) (10 total)...

The first build failure:
