Subject: [PATCH] hostcheck: fix host name wildcard checking
The leftmost "label" of the host name can now only match against single
'*'. Like the browsers have worked for a long time.
- extended unit test 1397 for this
- move some SOURCE variables from unit/Makefile.am to unit/Makefile.inc
Reported-by: Hiroki Kurosawa
Closes #11018
