Host init verifier already checks that the names and number of arguments for builtins are correct, but it can check more. This change ensures that property expansions are well formed, and that arguments that can be parsed on the host are correct. For example it checks that UIDs and GIDs exist, that numerical values can be parsed, and that rlimit strings are correct. Test: build Change-Id: Ied8882498a88a9f8324db6b8d1020aeeccc8177b
