dh_setup_copyright: Blacklist linux

The new implementation of dh_setup_copyright does not perform well on big packages like linux, causing OBS to abort the build. To workaround this issues create a blacklist of source packages for which the process should be skipped.

This approach was preferred to have a common place to track the source packages with issues and to avoid diverging branches, as currently both v2026dev1 and v2026dev2 use the same version of linux.
