package_deb: handle allarch when mapping tune to dpkg architectures

It was discovered that buildtools-tarball can't be built with Debian packaging:

E: Unable to locate package nativesdk-buildtools-perl-dummy

The package exists but dpkg doesn't see it because the Architecture field isn't
valid: for this package the Architecture field is 'allarch' which isn't in the
list of valid architectures we define.

package_deb already has a mapping of OE architectures (PACKAGE_ARCH) to dpkg
architectures (DPKG_ARCH), for example our x86_64 is amd64 in dpkg.  However
allarch.bbclass sets an invalid TARGET_ARCH of 'allarch' (to break anything
which attempts to use the target architecture) and package_deb relied on the
PACKAGE_ARCH check later turning the Architecture field into 'all'.

This usually works, but nativesdk-buildtools-perl-dummy inherits allarch but
then changes PACKAGE_ARCH to buildtools-dummy-nativesdk to isolate the packages
in a separate feed.  We can handle this by explictly checking for allarch in the
TARGET_ARCH check, as that everything that inherits allarch will want to have
Architecture: all in their packages.
