systemd-systemctl-native: Install systemd-sysv-install

It is needed when support for both systemd and sysvinit are enabled.

This also adds a patch for systemctl to call systemd-sysv-install
without a hardcoded path and instead relies on finding it in $PATH. This
is needed when calling systemctl from a recipe sysroot.

+Subject: [PATCH] systemctl: Call systemd-sysv-install without path
+
+Expect to find systemd-sysv-install in $PATH instead of hardcoding the
+path to it, as the latter does not work when running systemctl from a
+recipe sysroot.
