Description Philipp Hahn

"management/univention-management-console/dev/dh-umc-module-install" calls 'install' without '-p', so installed files use $NOW as their timestamp instead of preserving the timestamp of the source files. Two builds of the same package are thus not reproducible.

Today this complicated debugging a time stamp issue, where "update-python-modules" form "python-support" was not called due to "dh_strip_nondeterminism" not fixing the time stamps of some files.

Add "-p" for install calls:
