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.
