Fabian Homborg f58f2e14a3 tests/bind: Increase escape delay
We just had the following output on Github Actions:

 INPUT      +0.94 ms (Line 34): echo ghi jkl
 INPUT      +0.72 ms (Line 35): \x1b
 INPUT     +63.12 ms (Line 37): t\r

The default escape delay is 30ms, that had 60ms between an escape and
a tab, so it missed it.

So: We have to increase the delay for CI's benefit. Let's try with
80ms, because otherwise we'd have to bump up other timeouts and the
bind tests take long enough as it is.
