package/sdl2: fix build with kmsdrm

Browse Source 
Build with kmsdrm is broken since bump to version 2.0.14 in commit
5e0da5c40d. Indeed, first patch was
already applied in this version:
9354aea198
but upstream made other changes that requires EGL so add an upstream
patch to fix the build failure

Moreover, run autogen.sh instead of autoreconf as it breaks the build
and is not recommended by upstream:
https://github.com/libsdl-org/SDL/pull/4214

Fixes:
