build: include rules.mak from source, drop the build-top copy

rules.mak has no @...@ substitutions, so there is no reason to copy it into
the build top.  Point all 38 subdir Makefile.in includes at the source copy
directly -- ${MAGICSRC}/rules.mak instead of ${MAGICDIR}/rules.mak -- and
remove AC_CONFIG_FILES([rules.mak:rules.mak]) from configure.  defs.mak (the
one make fragment with substitutions) remains the only generated file in the
build top.  readline/ and the top Makefile never included rules.mak, so they
are unaffected; AC_CONFIG_SRCDIR(rules.mak) (the srcdir sentinel) is kept.

Now editing rules.mak in the source tree takes effect without reconfiguring.

Verified rc=0, 375 files, both in-tree and out-of-tree; out-of-tree build
top has no rules.mak; distclean rc=0.
