avcodec/h261dec: Don't initialize unused part of RLTable

The H.261 decoder only uses an RLTable's VLC table, yet it also
initializes its index_run, max_level and max_run. This commit stops
doing so; it will also simplify making this decoder init-threadsafe,
as the H.261 decoder and encoder now initialize disjoint parts of their
common RLTable.
