gnu: Remove gnash.

Gnash is unmaintained since 2019, does not compile with recent versions
of Boost, does not compile with C++17 and above and requires an older
version of GCC and deprecated dependencies.
It can be replaced by Lightspark in the majority of cases.

* gnu/packages/animation.scm (gnash): Delete variable.
* gnu/packages/patches/gnash-fix-giflib-version.patch: Delete patch.
* gnu/local.mk (dist_patch_DATA): Remove it.
