eglibc: fix mispackaging of libcidn

The glob for libc_baselibs was too permissive, causing some of the libcidn
symlinks to be placed in ${PN} rather than the intended subpackage.  Worse,
the .so itself was actually landing in ${PN}-dev, so the net effect was to
make libc6-dev a dependency of libc6.

Bump PRs for both 2.12 and 2.13 as a result.
