libc-common.bbclass: rename ALL the packages

libc-common.bbclass: rename ALL the packages

The DEBIAN_NAMES feature renames some of the libc packages to
"libc6*" names --but only some. A previous patch added the -dbg
package. However, this doesn't cover other packages (such as
the -doc package), and it didn't take multilibs into account.
