[Qemu-devel] [PATCH v3] vhost-user: disable the *broken* subprocess tests

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

tests/vhost-user-test keeps failing on build-system since Aug 15:

  ERROR:tests/vhost-user-test.c:835:test_flags_mismatch: child process (/i386/vhost-user/flags-mismatch/subprocess [4836]) failed unexpectedly
...
  ERROR:tests/vhost-user-test.c:807:test_connect_fail: child process (/x86_64/vhost-user/connect-fail/subprocess [58910]) failed unexpectedly

Suggested-by: Peter Maydell <peter.maydell@linaro.org>

v3: only disable tests using glib subprocess,
    migrate/multiqueue/guest-mem are still tested.

v2: remove unuseful warning
