avcodec/apedec: fix undefined left shifts of negative numbers
This fixes -Wshift-negative-value reported with clang 3.7+, e.g http://fate.ffmpeg.org/log.cgi?time=20150919172459&log=compile&slot=x86_64-darwin-clang-polly-notiling-3.7. Note that the patch crucially depends on int >= 32 bits, an assumption made in many places in the codebase.
