dpkg: Use bzip2-replacement-native

dpkg: Use bzip2-replacement-native

bzip2-native is in ASSUME_PROVIDED so the dependency that dpkg has doesn't correctly
trigger the build dependency. This shows up if you don't have bzip2 development
headers on your build machine and you:

bitbake dpkg-native
bitbake dpkg-native -c cleansstate
rm tmp -rf
bitbake dpkg-native

This patch uses the bzip2-replacement-native dependency as a handful
of other recipes do to make sure libbz2 is available.
