Subject: relocatable.bbclass: remove hard-coded rpaths from native binaries

The relocatable path will pre-process built binaries in SYSROOT_DESTDIR and
replace any harcoded dynamic link rpaths with relative paths.

Add an inherit of class in native.bbclass to make our native packages
relocatable and tweak the chrpath recipe so that the native package can make
itself relocatable with the just built chrpath binary.
