tests/prime_self_import: add subtest to export/import a second gem buffer

Browse Source 
Also add a subtest for the fd=handle_to_fd(), fd2=dup(fd), close(fd)
case (idea from Kristian Høgsberg).

Signed-off-by: Imre Deak <imre.deak@intel.com>

v2:
- add a new subtest instead of modifying the original test (Daniel)
- add a new subtest for testing dup (Kristian)
