Subject: avcodec/h263, h263data: Move ff_h263_init_rl_inter to h263.c

The SVQ1 decoder does not need mpegvideo or rl.c, but it uses stuff
from h263data.c. But since 61fe481586425a41d45e371de1e875b49882477d
h263data.c called ff_rl_init() and this of course led to build errors
when the SVQ1 decoder is enabled and mpegvideo disabled.

Fix this by moving ff_h263_init_rl_inter() to h263.c.
Fixes ticket #9224.
