[PATCH wayland-web V2] doc: Update ubuntu12.04 instructions to build expat from source

[Bill Spitzak]

Uses the tar file from the sourceforge repository. This avoids use of cvs
which would otherwise have to be installed.

The main purpose of this is to get a working pkg-config so the new
autoconf for wayland works, but since this updates from expat 1.6.0
to 2.1.0 it seems like a good idea.
