The cupsd.conf currently provided by the cups package contains a Kerberos
section. Since cupsd is built without gssapi support, the daemon fails
to verify it's configuration and refuses to start. This commit adds a
build option to make it possible to build the package with gssapi
support and also provides a patch pulled in from Alpine Linux for the
cupsd.conf to be able to start the daemon without building it with gssapi
support.
