Shift parameters so the pkg list doesn't include the destination.

This shift was forgotten in the earlier commit.
Install localized wikipedia search plugins (again).

Previously we got them from the iceweasel-l10n-* packages, but we do
not install them since the TBB migration.
TBB's Startpage search plugin has a different name (Closes: #8036)

... than the old one we used prior to the TBB migration, so our
branding addons wouldn't set it as the default for en-US (and locales
without a localized Startpage plugin, which falls back to en-US).
Drop unnecessary HTTPS part for Startpage search plugins.
Add localization helper functions for XUL applications.

That is for the various browsers and Tor Launcher. This will make it
possible to drop the browser localization code from Tails Greeter's
PostLogin script, where that really doesn't belong.

Also, this new code is an improvement in that it will pick a "similar"
locale if the specific one we look for isn't available. E.g. with
pt-BR we will get pt, and the Firefox is smart enough to use the pt-PT
langpack.
Use the new, improved localization code for the browsers and Tor Launcher.
Simplify the chroot browser's code slightly.
