Make MANAGER_TEST_RUN_MINIMAL just allocate data structures

When running tests like test-unit-name, there is not point in setting
up the cgroup and signals and interacting with the environment. Similarly
when running fuzz testing of the parser.

Add new MANAGER_TEST_RUN_BASIC which takes the role of MANAGER_TEST_RUN_MINIMAL,
and redefine MANAGER_TEST_RUN_MINIMAL to just create the basic data structures.
