Title: #3304: Make use of `named` well-known service
The systemd unit name of `named`(which is actually used) is platform-dependent:
debian - bind9-pkcs11.service
fedora - named-pkcs11.service
redhat - named-pkcs11.service
Other systems may have their own name of `bind` service.
But the default one (`named-pkcs11`) is assumed in many tests.
Of course, these tests fail on such platforms.
This can be easily fixed.
All platforms define well-known service `named`, which is linked to
the actually utilized one.
