emacs-29 6fe11b88ed0: Avoid using --display in emacsclient to reuse frames on PGTK

[Eli Zaretskii]

branch: emacs-29
commit 6fe11b88ed044f08680a174ce1b7677b1a5d9be1
Author: Davide Masserut <dm@mssdvd.com>
Commit: Eli Zaretskii <eliz@gnu.org>

    Avoid using --display in emacsclient to reuse frames on PGTK
    
    Using hard-coded display values can cause PGTK graphical frames to
    open using the wrong backend or not open at all.
    * Makefile.in (install-etc): Use --reuse-frame instead of
    --display=$DISPLAY.  (Bug#65509)
