rtmpdump: --HEAD builds cannot download sources

[ts826848]

Didn't get to do too much research on this, but I'll come back to it later.

For whatever reason the --depth 1 flag seems to cause the rtmpdump repo to immediately close the connection. Manually cloning the repo into the cache let the build progress.
