This is what I implemented:

--8<---------------cut here---------------start------------->8---
# At debhelper compat level 14, dh_installsystemduser will handle restarting
# tag2upload-oracled on package upgrade: see #1117735.
# We want this for the live service, but don't want to upgrade the whole
# package to compat 14 to preserve buildability on older releases of Debian.
# Debian::Debhelper::Dh_Lib::MAX_COMPAT_LEVEL has been available for a long
# time; if it isn't, that won't go by silently because intcmp will exit the
# build when it gets a non-numeric argument.
MAX_COMPAT_LEVEL=$(shell perl -MDebian::Debhelper::Dh_Lib \
		-we'print Debian::Debhelper::Dh_Lib::MAX_COMPAT_LEVEL')
override_dh_installsystemduser:
	$(intcmp $(MAX_COMPAT_LEVEL),14,,DH_COMPAT=14) \
		dh_installsystemduser --name=tag2upload-oracled --no-enable
--8<---------------cut here---------------end--------------->8---
