Lorenzo Colitti eb92f48b1d Move main() out of clatd.c.
This allows us to unit test methods that are in clatd.c.
Also simplify the build file, adding a defaults stanza and
grouping files in a filegroup so that both the code and the unit
test have the same source files.

Test: atest clatd_test
Test: builds, boots, 464xlat works
