build: Update copyright.

Claim copyright for all changes done over the years.
Copyright statements are already in most source files but
not in the generic version header and the command output.
So essentially this doesn't change anything already not
in effect already just makes it more prominent.

Also added the BAREOS copyright which was missing in the
comment section of version.h

src/include/version.h
