Remove some includes of readline.h

I went through most of the spots that include readline.h and, when
appropriate, either removed the include or changed it to include
tilde.h.

Note that remote-sim.c and bsd-kvm.c could probably include tilde.h
instead, but I did not change these.  I think I can't build the
latter, and I didn't want to set up a sim build for the former.

Tested by rebuilding.
