pgsql: Fix vcbuild failures and chkpass dependency caused by 854adb8

Fix vcbuild failures and chkpass dependency caused by 854adb8

Switching the Windows build scripts to use forward slashes instead of
backslashes has caused a couple of issues in VC builds:
- The file tree list was not correctly generated, build script
generating vcproj file missing tree dependencies when listing items in
Filter.
- VC builds do not accept file paths with forward slashes, perhaps it
could be possible to use a Condition but it seems safer to simply
enforce the file paths to use backslashes in the vcproj files.
- chkpass had an unneeded dependency with libpgport and libpgcommon to
make build succeed but actually it is not necessary as crypt.c is
already listed for this project and should be replaced with a fake name
as it is a unique file.
