apr-util: prevent recursive linking

004-avoid_ldap_by_defaut.patch:
 By default use --avoid-ldap since apache2 is the only user, and we don't
 want to add extra dependencies to other apr-utils rdepends. Patch from
 Ryan Niebur <ryanryan52@gmail.com>, copied from Debian.

005-apu_config_dont_list_indep_libs.patch:
 Prevent recursive linking of dependent libraries by apr-util users.
 Patch from Peter Samuelson <peter@p12n.org>, also copied from Debian.
 Makes libexpat and libiconv private.

006-avoid_db_by-default.patch:
 Make apu-config not output dbm libs by default. See Debian #622081.
 Patch from Stefan Fritsch <sf@debian.org>, also copied from Debian

While bumping the revision also correct license information.
