[FFmpeg-cvslog] avcodec, avformat/ffjni: fix duplicate JNI symbols

[Leo Izen]

ffmpeg | branch: release/7.0 | Leo Izen <leo.izen at gmail.com> | Wed Mar 27 09:06:19 2024 -0400| [9a4c7b937f4b804a023a9949d1250a332b33107c] | committer: Matthieu Bouron

avcodec, avformat/ffjni: fix duplicate JNI symbols

Use SHLIBOBJS and STLIBOBJS in the Makefiles for avcodec and avformat,
and add a stub ffjni.c to libavformat, which allows the symbols to be
duplicated for shared builds but not static builds.
