ACK/cmnt: [PATCH v2 1/1] ubuntu_lxc: lxc-tests is deprecated - fetch tests from origin

[Po-Hsu Lin]

This patch is good, but I just found that not all test binaries were
pre-built there.

Compare the test result from Artful, there are 39 tests shipped by the
lxc-test package, but only 10 pre-built executables from the repo.

Consider this can be fixed in the next step, I will give my ack here.
Thanks.
