Revert systemd interface version to 2
The new systemd in 19.09 gives an "Access Denied" error when doing
"systemctl daemon-reexec" on an 19.03 system. The fix is to use the
previous systemctl to signal the daemon to re-exec itself. This
ensures that users don't have to reboot when upgrading from NixOS
19.03 to 19.09.

# On aarch64 we "leak" a reference to $out/lib/systemd/catalog in the lib
# output. The result of that is a dependency cycle between $out and $lib.
# Thus nix (rightfully) marks the build as failed. That reference originates
# from an array of strings (catalog_file_dirs) in systemd
# (src/src/journal/catalog.{c,h}). The only consumer (as of v242) of the
# symbol is the main function of journalctl. Still libsystemd.so contains
# the VALUE but not the symbol. Systemd seems to be properly using function
# & data sections together with the linker flags to garbage collect unused
# sections (-Wl,--gc-sections). For unknown reasons those flags do not
# eliminate the unused string constants, in this case on aarch64-linux. The
# hacky way is to just remove the reference after we finished compiling.
# Since it can not be used (there is no symbol to actually refer to it) there
# should not be any harm. It is a bit odd and I really do not like starting
# these kind of hacks but there doesn't seem to be a straight forward way at
# this point in time.
# The reference will be replaced by the same reference the usual nukeRefs
# tooling uses. The standard tooling can not / should not be uesd since it
# is a bit too excessive and could potentially do us some (more) harm.
