[Bug]: `ffmpeg7` and `ffmpeg5.1` do not work anymore

[robertkirkman]

Problem description

ffmpeg7 and ffmpeg5.1 do not work currently

~ $ ffmpeg5.1 
CANNOT LINK EXECUTABLE "ffmpeg5.1": library "libxml2.so.2" not found: needed by /data/data/com.termux/files/usr/opt/ffmpeg5.1/lib/libavformat.so.59.27.100 in namespace (default)
~ $ ffmpeg7 
CANNOT LINK EXECUTABLE "ffmpeg7": library "libxml2.so.2" not found: needed by /data/data/com.termux/files/usr/opt/ffmpeg7/lib/libavformat.so.61.1.100 in namespace (default)
~ $ 

also, maybe ffmpeg7 is very redundant with ffmpeg from the main repository - currently. I almost thought I should ask for ffmpeg7 to be disabled. But when I think of the future, some day ffmpeg in the main repository will be updated to version 8. and then after that, there wouldn't be ffmpeg version 7 in Termux anymore unless ffmpeg7 is preserved. Maybe ffmpeg7 in TUR exists now to prepare for that so that if there is something wrong with ffmpeg version 8 in the distant future, people will be able to go back to use version 7 by installing ffmpeg7 from TUR.

Also, I decided not to increase dependencies to be exactly the same as ffmpeg from the main repository, because I have been increasing the dependencies of that one, but someone has been asking for ffmpeg dependencies to be reduced, not increased. Maybe these TUR FFmpeg packages could be helpful for that person a little bit, if they are looking for alternatives that don't use quite as much space. See:

• Optional ffmpeg deps termux/termux-packages#26222
• addpkg(main/ffmpeg-minimal): 7.1.1 termux/termux-packages#26243

What steps will reproduce the bug?

pkg install tur-repo
pkg install ffmpeg7
ffmpeg7

What is the expected behavior?

ffmpeg7 and ffmpeg5.1 working
