Re-eneable tcp evasions in some LoginScanners

Fixes #3967.

In the switch to LoginScanners we lost `TCP::max_send_size` and `TCP::send_delay` evasion options for most of the `*_login` modules.

`HttpClient` has never supported them.

#### Verification
 - [ ] start wireshark
 - [ ] `use` any of the modified scanners
 - [ ] `set TCP::max_send_size 1`
 - [ ] `run`
 - [ ] **Verify** wireshark shows 1-byte TCP packets
