Description: Fix to check for avutil.h in a path where newer versions of ffmpeg install the header
Origin: OpenSDE (http://opensde.org)

This fix also implies the to explicitely pass -D__STDC_CONSTANT_MACROS to get
the UINT64_C macro from stdint.h which is used in libavutil/common.h.

Furthermore the check for avutil.h at the old location has been preserver, but
is only used as a fallback when there was libavutil/avutil.h was found.
