msvc: fix make test without having to play PATH games

When building with Microsoft Visual C, we use NuGet to acquire the
dependencies (such as OpenSSL, cURL, etc). We even unpack those
dependencies.

This patch teaches the test suite to add the directory with the unpacked
.dll files to the PATH before running the tests.
