scripts/jenkins-yoctobuild-build: run enterprise backend-integration

moving forward, tests are named '-Enterprise' instead of
'-Multitenant'. hence we'd ideally like to run chained
'not Enterprise' && 'Enterprise' tests (with the new enterprise layer).

mender-qa must handle older releases too, which means two cases:
1. have old MT layers, and old 'Multitenant' tests
2. already have new 'enterprise' layer, but still old 'Multitenant'
tests (transitional)

in case 2, MT simply cannot be ran. in case 1 they could, but then
they're unnecessary - if we're going back to older releases, it's to fix
the onprem setup. so - to avoid extra logic, just skip on Multitenant
tests always.
