[PATCH][weston] build: don't duplicate rule for weston.desktop

[Ross Burton]

dist_wayland_session_DATA will distribute and install src/weston.desktop, so the
definition of wayland_session_DATA which also installs src/weston.desktop will
result in the file being installed twice and (rarely) cause install to fail.

Spotted and fix by Roy Li <rongqing.li at windriver.com>.
