lavf/srt: fix build fail when used the libsrt 1.4.1

libsrt changed the:
SRTO_SMOOTHER   -> SRTO_CONGESTION
SRTO_STRICTENC  -> SRTO_ENFORCEDENCRYPTION
and removed the front of deprecated options (SRTO_SMOOTHER/SRTO_STRICTENC)
in the header, it's lead to build fail

fix #8760

Signed-off-by: Jun Zhao <barryjzhao@tencent.com>

So, this patch and the patch from #968574 would be great!

Thanks,
Adrian
