[OE-core] [PATCH] package_rpm.bbclass: improve reproducibility of RPM packages

[Juro Bystricky]

The RPM packages contain BUILDHOST based on the current build host.
This breaks reproducibility if the same package is build on two different hosts.
To improve reproducible builds, we always set BUILDHOST as "reproducible".
