[zircon][unittest] Provide default main function in unittest library

This removes an inordinate number of boilerplate copies of the standard
main function for a test.  In the case of the core tests it (mostly)
obviates the need to compile each source file separately for standalone
and all-in-one incarnations, which the new build will take advantage of.
