Remove trailing newlines from help text

I noticed recently that some command had a trailing newline in its
"help" output.  So, I temporarily hacked cli-decode.c to print
something when a new command was installed that had a trailing newline
in its help message, and wrote this patch, which removes all the ones
I could find this way.  (There could still be a few more in *-nat
files.)

Tested on x86-64 Fedora 29.
