make dist: Use fewer wildcards

The remaining ones only work by accident:
  http://www.gnu.org/software/automake/manual/html_node/Wildcards.html
and they have some practical problems too (we don’t really want to
distribute include/urweb/config.h or src/config.sml), but this is
enough for now to pass ‘make distcheck’ as long as we don’t run it
from a separate build directory.
