test(xcat-core): capture Subiquity install failing when installnic is unset

Browse Source 
The Ubuntu diskful (Subiquity) install fails on any node that does not set
noderes.installnic. compute.subiquity.tmpl resolves #TABLE:noderes:$NODE:installnic#,
and Template.pm's tabdb raises "Unable to find requested field <installnic> from
table <noderes>" when the value is absent, aborting with "Failed to generate xnba
configurations" so the compute node never enters the installer. EL and SLES pass the
identical case because their statefull templates never reference installnic
(gen_net_boot_params defaults to the boot MAC).

Assert that the template uses the non-fatal #TABLEBLANKOKAY# token for installnic and
treats an empty installnic the same as "mac" (match by MAC, no NIC rename). These
assertions fail on the current template, capturing the defect.
