tests: Add test package for libdbuspolicy - again
This reverts commit
376f38dafa0b7ee5eae3d8f0ba0333c84a79742d,
which reverted commit
bb7d32bb63f1d0fc463255000fbc773a119314a9.
This is different from commit
bb7d32bb63f1d0fc463255000fbc773a119314a9
in handling builds - it provides single spec file.
Additionally, corrections for tests, mostly
excluding initialization of the library from "test cases".
