xdg-desktop-portal: Upgrade 1.18.0 -> 1.18.1

Current meson.build fails if flatpak was not found using pkgconfig
../git/meson.build:203:44: ERROR: Unknown variable "flatpak_dep"

Removing -Dflatpak-interfaces-dir setting and relying on pkgconfig
for flatpak instead seems to work well in our case and avoids the error above

This is a new minor release of xdg-desktop-portal 1.18 series. Users and
distributions are strongly encouraged to update to this version. These are the
changes included in this release:

    -Communicate better when the Background portal kills an app
    -Properly quote Flatpak command in the Background portal
    -Improve documentation of the "cursor_mode" propery of the ScreenCast backend
     D-Bus interface
    -Fix ScreenCast portal removing transient restore permissions too early.
     This fixes screen sharing dialogs on Chromium asking for the screen multiple
     times.
    -Only send the Closed session signal to the sender
    -Add Meson options to disable building with Bubblewrap, and without the
    -Flatpak portal documentation. Disabling Bubblewrap is highly discouraged,and
     only meant to be used on platforms that do not currently support it. By
     disabling Bubblewrap, bitmap validation happens without a sandbox, which is
     highly insecure since image parsing is a common source of exploits. Really, just
     do not disable Bubblewrap please.
    -Improve the manpage of portals.conf
    -Various spelling fixes to the Document portal
    -Add a new website! We don't have a fancy domain yet, but the website can be
     accessed at https://flatpak.github.io/xdg-desktop-portal/
    -Improve pid mapping for host system apps. This should get rid of some rare,
     unnecessary warnings.
    -Adjust documentation of Global Shortcuts portal's timestamps to millisecond
     granularity
    -Bump minimum Meson version to 0.58
