Fedora's build environment runs inside a systemd-nspawn(1) container and
runs into this test failure:
  ...
  ...
  Adding library /lib/libcap.so.2
  Adding library /lib/libpcre2-8.so.0
  Adding library /lib/libselinux.so.1
  Adding library /lib/libtinfo.so.6
  error: /tmp/tmp.ppnOBuhUOv/export/share/icons/hicolor/64x64/apps/org.test.Hello.png
      is not a valid icon: bwrap: Can't mount proc on /newroot/proc:
      Operation not permitted
  OK closing connection
  (test program exited with status code 1)

... which, otherwise, passes when run interactively on a Fedora
Workstation 39 system.

It is the 'flatpak build-export ...' call in tests/make-test-runtime.sh,
which calls 'flatpak-validate-icon --sandbox' to validate the icons in a
bwrap(1) sandbox.  This used to work in the recent past, even with the
build running inside a systemd-nspawn(1) container, but not anymore,
likely because of other changes in the build environment.

Therefore, there's no point in blocking flatpak-builder builds until the
tests are fixed.
