tests/resource: set grant version for created domains

Set the grant table version for the created domains to use version 1,
as that's the used by the test cases. Without setting the grant
version the domains for the tests cannot be created.

Fixes: 7379f9e10a ('gnttab: allow setting max version per-domain')
