www/firefox-esr: expose PipeWire support after c58401d4dda5

Should work on wlroots-based compositors. For example,

  # pkg install firefox sway pam_xdg xdg-desktop-portal-wlr xdg-desktop-portal
  # sysrc seatd_enable=YES
  # service seatd start
  # echo 'session optional pam_xdg.so notroot runtime' >>/etc/pam.d/system
  $ exit # log out to pick up XDG_RUNTIME_DIR
  <new login>
  $ export XDG_CURRENT_DESKTOP=sway
  $ export MOZ_ENABLE_WAYLAND=1
  $ dbus-daemon --session --fork --address=unix:runtime=yes
  $ sway
  <GUI session>
  $ dbus-update-activation-environment --all
  $ daemon -f pipewire
  $ firefox https://mozilla.github.io/webrtc-landing/gum_test.html
  <click on "Screen Capture">
  <select "Use operating system settings">
  <click on "Allow" button>
  <select via cursor the desired screen (output display)>
  <notice the screen mirrored on the web page>
