[meta-oe][PATCH 7/9] xdg-dbus-proxy: skip ptest when dbus-daemon is unavailable

From: Khem Raj <[email protected]>

tests/test-proxy.c setup() spawns the reference bus implementation
directly:

  g_subprocess_launcher_spawn (launcher, &error, "dbus-daemon",
                               "--session", "--print-address=1",
                               "--nofork", NULL);

so the test aborts on distros that select a different
VIRTUAL-RUNTIME_dbus:

  ERROR:../tests/test-proxy.c:75:setup: assertion failed (error == NULL):
  Failed to execute child process "dbus-daemon" (No such file or directory)
  FAIL: xdg-dbus-proxy/test-proxy.test (Child process killed by signal 6)

dbus-daemon is packaged only in dbus, and dbus-broker carries
"RCONFLICTS:dbus-broker: dbus", so the two cannot be co-installed;
dbus-broker-launch is not CLI-compatible and cannot stand in. The
existing RDEPENDS on ${VIRTUAL-RUNTIME_dbus} already pulls in dbus (and
hence dbus-daemon) on distros that use it, so report the test as skipped
rather than failed when the daemon genuinely is not installable.
