Several bug fixes

Completes the logic for checking UUID instead of XclbinId on F1 (#890)

* parse uuid on F1 instead of expecting xclbinid

* Get uuid from axlf for comparisson. Tested and passes on F1.

* Using uuid_compare, and making xclGetXclbinUuid() a const function.

* Fix comparisson to 0, and use uuid_is_null instead
