tests: verify that NIX_DAEMON_PACKAGE's version looks like a version

Browse source 
Followup to https://gerrit.lix.systems/c/lix/+/1417 to ensure that this
parser will never take something that doesn't look like a version.

It turns out this problem is less alarming than initially thought
because it only applies to the testsuite in a non-default mode.
