libfdk-aacenc: Enable 7.1 channel encoding
7.1(wide) and 7.1(wide-side) channel layouts are supported in
fdk-aac since the 0.1.3 release.
The earlier versions of fdk-aac didn't include any library
version defines in the public headers, thus checking for
the AACENCODER_LIB_VL0 define is enough to know that we're
building against a new enough version of fdk-aac.
This change includes contributions by Tim Walker,
Michael Niedermayer and Timothy Gu.
