We also instruct the RM to check the url with https for some added
authentication.

We didn't do this prior to the TBB 4.x bump; 4.x's new directory
layout caused this, so now these must be explicitly deleted.

This instance was forgotten before.

It was a relic of the TBB 3.x times when the profile was located in
the parent directory of the TBB browser files.

Also patch Tails Greeter with the updated path. That patch should
be dropped once it's been upstreamed into Tails Greeter.

The new place corresponds better to where Debian puts the Iceweasel
extensions. Also, it will allow us to drop the useless "Browser"
sub-dir in TBB_INSTALL without having potential collisions (e.g. if
there was a "Browser/extensions").

... and that makes it available in the Tor Browser.

This was likely caused by a copy-paste error.

Patch from Kill Your TV.
