o Adding information regarding the *package-metadata* option for the *tar*
service The tar service is highly useful in combination with the *obscpio*
service. After the fix for the metadata for the latter one, it is important
to inform the users of the *tar* service that metadata is kept only if the
flag *package-metadata* is enabled. Add the flag to the .service file for
mentioning that.
o Allow metadata packing for CPIO archives when desired As of now, metadata
are always excluded from *obscpio* packages. This is because the
*package-metadata* flag is ignored; this change (should) make *obscpio*
aware of it.

o don't allow DEBUG_TAR_SCM to change behaviour (#240)
