[OE-core] [meta-oe][PATCH v2] rpm: fix rpm path in nativesdk

[Zhaolong Zhang]

Fix the incorrect path inside the nativesdk 'rpmdeps' wrapper:

In os.path.relpath(), it was assumed that all the WRAPPER_TOOLS are in {bindir},
and all the relative paths was calculated based on {bindir}.

However, the assumption was not true for 'rpmdeps' because it is in {libdir}/rpm/.
So the path in rpmdeps wrapper was incorrectly calculated to ..../usr/lib/lib/rpm.

To fix this, we can simply use $OECORE_NATIVE_SYSROOT as the base path, instead of
the complicated runtime path calculation.

The patch also fix the hard coded path in 'find-provides' and 'find-provides' for
nativesdk.
