Merge 32770 - Revert change that disallowed content scripts access to
file:// URLs. It turns out teams were already depending on
this and we didn't want to break them.

Instead, group file:// access with NPAPI in the extension
install prompt.

Note: this is a pure revert of r402029 and r402069 (sorry
Finnur!) except the changes in extension_install_ui.cc,
which are new.
