games-strategy/widelands: drop use of cxxflags patch

-Werror=uninitialized cause issues with -O3. Upstream is currently
explicitly requesting -O2 but an old patch in Gentoo prevents that.

While not ideal, rather than further patch to remove the warning check,
simply follow upstream and go with what is being tested more.
