[Buildroot] [git commit] minidlna: fix build failure

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=aab5d679e72f11d4b405d63803663896bb69a98c
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

With the 1.0.26 version bump a new routine was added to find newer
versions of ffmpeg and/or libav on different include paths.
Unfortunately this uses absolute pathnames hence when there's no
matching ffmpeg/libav headers on the host it fails to build. Fixes:
