It is failed to build with systemd, the rpm's sysuser creation doesn't work with
cross build, and we don't need rpm to create the users since we have
useradd.bbclass. The fix is:

diff --git a/meta/classes-global/package_rpm.bbclass 
b/meta/classes-global/package_rpm.bbclass
index 1b86cb52cd..e85644995a 100644

I will send a V8 after more testing.
