apport should fallback to console mode after "shm_open() failed: permission denied"

[Karl-Philipp Richter]

`shm_open() failed: permission denied` usually happens in a `chroot`, but might have other causes as well. In this case `apport` should not try to open the default browser, but offer the console based dialog like in a SSH session.
