[PATCH 4/6] package_rpm.bbclass: Filter out unwanted file deps for nativesdk packages

[Mark Hatle <mark.hatle@windriver.com>]

From: Peter Kjellerstedt <pkj@axis.com>

Filter out any file dependencies on absolute paths and any
dependencies on Perl modules for nativesdk packages. It is assumed
that they will be provided by the native host if needed, and they mess
up the dependency handling if they are present.
