avutil/crc: avoid needless space wastage of hardcoded crc table
There was no reason AFAIK for making AV_CRC_24_IEEE 12. This simply
resulted in wasted space under --enable-hardcoded-tables:
dynamic: 1318672 libavutil/libavutil.so.55
old : 1330680 libavutil/libavutil.so.55
new : 1326488 libavutil/libavutil.so.55
Minor version number is bumped, with ifdefry due to API breakage.
