[PATCH] sstate: Add extra entries to the sstate duplicate files whitelist

[Richard Purdie <richard.purdie@linuxfoundation.org>]

This avoids errors where gcc/binutils get installed to the native sysroot
in the same location for multiple package architectures. Ultimately making
these native recipes with ${PACKAGE_ARCH} appended to PN will resolve this
but hide the warnings until this gets sorted out.

Also hide the python and docbook catalog warnings since they're known about,
nothing to worry about and we'll aim to clean them up properly in the 1.4 cycle.
