Subject: dpkg: export DPKG_LIBDIR to maintainer scripts

It can be used to find out the location of some internal dpkg programs
that might be called from maintainer scripts. That way we can avoid
hardcoding /usr/lib/dpkg and maintainer scripts will still work when
called from a dpkg manually installed in /usr/local for example.
