vcxproj: also link-or-copy builtins

The problem with not having, say, git-receive-pack.exe after a full
build is that the test suite will then happily use the *installed*
git-receive-pack.exe because it finds nothing else.

Absolutely not what we want. We want to have confidence that our test
covers the MSVC-built Git executables, and not some random stuff.
