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

[Bill Spitzak]

This git repository was the best one I found. Even then the instructions
seem to be wrong, there was no buildconf script and the execute bit was
not turned on for configure.

This seems to work and I confirmed that the output of wayland-scanner
matches the versions in the wayland repository.
