Please exclude make_binary_distribution from the distribution

With cmake (5.5 and up), "make package" will do it,
or cpack.
The (generated) "scripts/make_binary_distribution" is just
a wrapper around a "cpack" call,
with path names set at build time.

Similar, "make_win_bin_dist" is not needed any more.

scripts/CMakeLists.txt:
  Cleanup:
  Append a trailing newline when generating "make_binary_distribution"
  (which is just a wrapper around a "cpack" call).
support-files/mysql.spec.sh:
  "make_win_bin_dist" is removed from the sources,
  so its man page is gone,
  and it need not be removed when creating the RPMs.
