Subject: win32: fix RUBY_RELEASE_DATE in Makefile

As it is overridden by the definition in common.mk, instead define
YEAR, MONTH and DAY which are used there.

This macro is useful for daily build&installation by the
combination with "relative-load", for example:
```sh
$ ./configure --prefix=/. --enable-load-relative \
  --with-destdir='$(HOME)/.rbenv/versions/$(RUBY_RELEASE_DATE)'
```
This can install images usable by rbenv per days.
