Configure: add missing dependency to fix parallel builds on Windows

Configure: add missing dependency to fix parallel builds on Windows

The issue was encountered when testing parallel builds of OpenSSL on
Windows using `jom` instead of `nmake`. The builds persistently failed
with the following error message because the generated file "buildinf.h"
did not exist yet.

crypto\info.c(15): fatal error C1083:
    cannot open include file: "buildinf.h": No such file or directory

Apparently this error does not occur on Linux because `make` parallelizes
the builds differently such that `crypto\cversion.c`, which has an
explicit dependency on `buildinf.h`, gets compiled first. Also, the
include dependency was added only recently in commit 096978f0990.
