Remove setup0.h files from the list of headers in bakefile.

Remove setup0.h files from the list of headers in bakefile.

These headers don't exist in official distributions as they're renamed to
setup.h in them. Moreover, they don't need to be installed anyhow when using
configure as the real setup.h is installed specially, so there is no real need
to have them in the list of headers.
