Make pgwin32_putenv() visit debug CRTs.

This has no effect in the most conventional case, where no relevant DLL
uses a debug build.  For an example where it does matter, given a debug
build of MIT Kerberos, the krb_server_keyfile parameter usually had no
effect.  Since nobody wants a Heisenbug, back-patch to 9.2 (all
supported versions).
