[PULL v2 03/11] tests/docker: allow user to override check target

["Alex Bennée" <alex.bennee@linaro.org>]

This is useful when trying to bisect a particular failing test behind
a docker run. For example:

  make docker-test-clang@fedora \
    TARGET_LIST=arm-softmmu \
    TEST_COMMAND="meson test qtest-arm/qos-test" \
    J=9 V=1
