Add Debian's x-www-browser to the end of the Linux fallback chain

(This alias is created and maintained by Debian's "alternatives" system,
which is integrated with the APT package manager. It serves to act as
a system-wide default on Debian-family distros (eg. Ubuntu, Mint) which
applications can fall back to if the user hasn't specified a preference.)
