[Buildroot] [git commit branch/2020.08.x] package/rauc: disable systemd for host build

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=9f64d89f7e7c1c6935a5b9756527b6bc1389fdd5
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.08.x

Since there is not necessary to have support of systemd within the host
variant let's disable it unconditionally to solve the following errors:

/usr/bin/install -c -m 644 data/rauc.service '/usr/lib/systemd/system'
/usr/bin/install: cannot create regular file '/usr/lib/systemd/system/rauc.service': Permission denied
/usr/bin/install -c -m 644 data/de.pengutronix.rauc.conf 'no'
make[4]: *** [Makefile:1700: install-nodist_systemdunitDATA] Error 1
make[4]: *** Waiting for unfinished jobs....
