Andreas Rheinhardt 3e0bd5064d 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.
