lib/oe/rootfs: fix log_check warnings being printed twice with RPM packaging
We were calling _log_check() in the RPM-specific rootfs class as well as
in the base class; this is unnecessary and resulted in any errors/warnings
generated during the actual package installation time triggering two warnings
instead of one. Drop the call from RpmRootfs._create() to fix this.
