Fdk-aac 2.0 dropped some legacy APIs, breaking the build of the fdk-aac
plugin.  Add two upstream upstream patches to fix building against fdk-aac
2.0.

+Subject: [PATCH] fdkaacdec: Use WAV channel mapping instead of interleave
+ setting
+
+The latter is going away in libfdk-aac 2.0.0. Instead, MPEG-style output
+is always non-interleaved and WAV-style output is always interleaved.
+Earlier libfdk-aac also defaults interleaving accordingly.
+
+Since our reordering looks at the associated PCE indices instead of the
+actual channel order, we're agnostic to the mapping.
