If SVC is used, the minimum bitrate would be 30kbps, instead of 49, as
configured in svc_config.h, because the overall stream will get min_bitrate
from the default VP8 simulcast configuration, and this 30kbps will be
allocated to the stream for svc_rate_allocator to divide between layers.
However, with the configuration before this change, 49kbps would be always
allocated to the lowest simulcast stream.
