[fish] Remove perl from fish key bindings (#1635)

Browse Source 
Perl was used to remove the trailing newline character, but fzf already
has --print0 to use null character as terminators, and fish read -z is
expecting null character as terminators. There is no reason to depend on
perl if --print0 is passed to fzf invocation.
