api: POST /containers/{id}/wait: fix validation for "condition" parameter

commit 737e8c6ab8 added validation for the wait
condition parameter, however, the default ("not-running") option was not part
of the list of valid options, resulting in a regression if the default value
was explicitly passed;

    docker scan --accept-license --version
    Error response from daemon: invalid condition: "not-running"

This patch adds the missing option, and adds a test to verify.

With this patch;

    make BIND_DIR=. DOCKER_GRAPHDRIVER=vfs TEST_FILTER=TestWaitConditions test-integration
