vcxproj.pm: fix AdditionalDependencies

Add .LIBs for zlib and openssl to <AdditionalDependencies>
to help linker when building with VS2017.

This closes #1234

Note: this patch still leaves a couple of TODOs:

- It should be possible to add GEN.DEPS\lib to
  <AdditionalLibraryDependencies> and then just set
  <AdditionalDependencies> to the library basenames.

- Likewise, you should be able to copy GEN.DEPS\bin\*.dll
  to the destination directory rather than using the full
  paths in the $afterTargets lines.

(This is in line with items in <AdditionalIncludeDirectories>
referencing GEN.DEPS\include.)
