[vte] vte.sh: Use the vte-urlencode utility

[Christian Persch <chpe src gnome org>]

commit 115db9c2b4d07ab7bcd98c287c39854649bd2750
Author: Carlos Santos <casantos redhat com>
Date:   Wed Jan 22 18:06:28 2020 +0100

    vte.sh: Use the vte-urlencode utility
    
    Drop the __vte_urlencode function and use the vte-urlencode-cwd utility,
    instead of it, in __vte_osc7.
    
    Also call __vte_osc7 directly in __vte_prompt_command, instead of in a
    subshell, avoiding an extra fork.
    
    Drop the __vte_urlencode test, since the function does not exist anymore
    and vte-urlencode-cwd has its own test.
