srt: fix build issue with recent SRT library

The deprecated macro `SRTO_TSBPDDELAY` has been deleted from SRT.
This prevents the compilation with SRT versions >= v1.4.2.

See the corresponding SRT commit 0e2201aff6b379979cec43fee5e8f162717f6346.
```
-   SRTO_TSBPDDELAY = 23,     // DEPRECATED. ALIAS: SRTO_LATENCY
```

The (unrecommended) `SRTO_LATENCY` should be used instead, which was
already available back then. See notice next to SRTO_LATENCY in the SRT
library source code for details on why it's not recommended.
