[OE-core] [PATCH 1/1] package_manager.py: add noarch to buildarch_compat

[kai.kang at windriver.com]

From: Kai Kang <kai.kang at windriver.com>

It fails to run rpmbuild to build a noarch package on target when it
contains 'BuildArch: noarch' in the spec file:

| error: No compatible architectures found for build

Add 'noarch' to buildarch_compat in configure file rpmrc to fix it.
