Test times out if target is called "env"

When the target passed to labgrid_test.src is called "env" , the test times out:

subprocess.TimeoutExpired: Command 'cd /tmp/tmp.Ge30Dgq0LB-EXECROOT && /tmp/tmp.fWu0Y8VWGT-TOOLS/env 'XML_OUTPUT_FILE=results.xml' 'BAZEL_TEST=1' ./env' timed out after 30.0 seconds

Reproduction

py_binary(
    name = "env",
    srcs = ["env.py"],
    deps = ["@rules_python//python/runfiles"],
)

labgrid_test(
    name = "test",
    src = ":env",
    platform = "@rules_labgrid//labgrid/platform:localhost",
)
