gnutls.inc: allow libidn support to be controlled via PACKAGECONFIG

libidn (Internationalized Domain Name support library) may not be
desired in all cases, so add a PACKAGECONFIG option to control it.

Allow --enable-doc, libtasn1 internal -vs- external (still internal
by default) and p11-kit support to be controlled via PACKAGECONFIG
too.
