Bug#1007754: libgcrypt20: clean-up-unmanaged-libraries breaks foreign architecture DPKG_ROOT support

Hi,

the script clean-up-unmanaged-libraries does not support DPKG_ROOT which
breaks creating foreign architecture chroots with dpkg
--force-script-chrootless. Instead of adding DPKG_ROOT support to
clean-up-unmanaged-libraries it seems that this script is only useful
when upgrading libgcrypt20 and is not necessary for new installations of
the package. Because DPKG_ROOT is only used for new installations, an
easy fix to this situation is to run clean-up-unmanaged-libraries only
on upgrades and not on new installations.

I created the following merge request that fixes this issue:

Thanks!

cheers, josch
