configure: check avisynth header version

Browse Source 
The headers from version 3.7.1 are needed in order to support
parsing of frame properties. avs/version.h has been generated
as part of the AviSynth+ build process for a long time, but was
never installed with the includes until version 3.7.1a. Checking
for the presence of avs/version.h might have been sufficient,
but a version check mechanism might be useful in the future.

This does not change the version compatibility with the library
itself; previous 3.x versions of AviSynth+ as well as AviSynth 2.6
can still be used with the demuxer.
