fix(xcat-core): a correct hierarchical provision fails the provisioning-source check

check_provisioning_source.sh required the management node's httpd access log to gain
lines after the baseline. The three hierarchy cases take the baseline after
SN_setup_case has provisioned the service node. After that point a correct hierarchical
provision leaves the management node serving nothing, so its log does not grow. On the
xcat42 EL9 cell the service node served the compute node 252 boot-payload requests and
the management node served 0, and the check still reported "no httpd access log with
new entries could be read on xcat42-mn-dhilst".
reg_linux_diskless_installation_hierarchy failed for that message.

The guard now requires the log to hold lines, not to hold new ones. An empty log still
fails, because it makes "the management node served nothing" a property of the file
instead of a measurement.

check_provisioning_source.bats asserted the removed behavior in "a management node log
with nothing new fails the check instead of reading as silence". That case now asserts
the opposite, and a second case covers the empty log. Both fail against the unfixed
script.
