test-bundle2: dump bundle content using f --hexdump

Thanks to Greg Szorc for pointing this out.

 This test is dedicated to test the bundle2 container format
 
 It test multiple existing parts to test different feature of the container. You
 probably do not need to touch this test unless you change the binary encoding
 of the bundle2 format itself.
 
 Create an extension to test bundle2 API
