Add artd unit tests.

This change adds `art_artd_tests`, which contains the unit tests of
artd. The change also splits the code into artd.h/artd.cc and
artd_main.cc, where artd.h/artd.cc contains the implementation that is
unit-testable, while artd_main.cc contains the main function of the artd
binary.

Note: The test is not enabled because it currently doesn't work on
master-art.
