[packman] Avidemux build failure

[Wolfgang Bauer]

Hi!

I just noticed that avidemux (and avidemux2) fails to build on Tumbleweed.
It's also uninstallable now because of other updates, as has been brought up 
in this forum thread:
https://forums.opensuse.org/showthread.php/530573-How-to-install-avidemux

I had a look at the build log, and the problem seems to be this:
https://sourceforge.net/p/avidemux/bugs/77/

The fix is simple though:
https://github.com/mean00/avidemux2/commit/afdd9c4b876d77a4974d3fa7d9f25caeffbdf13d
(should apply as-is to avidemux2 as well, I suppose)

Would be great if somebody could add this patch to the packages... ;-)
Thanks.

Kind Regards,
Wolfgang
