pwntools: Collapse recvuntil + send into a single sendafter

[peace-maker]

When exporting a stream as a pwntools script, make the output a bit nicer by using the send[line]after functions instead of recvuntil + send[line].

This shortens the script and makes it more readable. The data chosen to receive until is the last line including newlines to try to make it unique.
