avcodec/mpeg4videodec: Don't initialize unused RL VLCs The RLTables whose VLC tables are only used for intra blocks only use the very first VLC table; yet all 32 have been initialized. This commit stops this by switching to INIT_FIRST_VLC_RL. This saves 201624B from the .bss segment; in case the decoder is actually used, this translates into less memory used.
