virshtest: Adapt 'virsh-checkpoint' test

Browse Source 
Invoke the majority of the command via DO_TEST_SCRIPT in 'virshtest'.
Some adaptation was needed to avoid printing of tables with volatile
data such as checkpoint creation time, which were converted to list
names-only.

To proprely test redefinition we store XMLs rather than taking them from
the defined checkpoints and use them separately to test redefinition of
checkpoint XMLs. This makes use of the 'cd' command in non-interactive
mode.
