net-proxy/http-replicator: Revert 3.0 branch removal

This reverts commit 3b8b8f6ec45e0220e5b841c96f89f52c6c5e02a5.
The 4.0 branch does not implement --alias which means it is not a
drop-in replacement to 3.0 in all cases.
Please speak to me or file me a bug if you have any change requirements
for the 3.x branch ebuilds. I will action them.
