cmake: add a preparatory work-around to accommodate `vcpkg` 

We are about to add support for installing the `.dll` files of Git's
dependencies (such as libcurl) in the CMake configuration. The `vcpkg`
ecosystem from which we get said dependencies makes that relatively
easy: simply turn on `X_VCPKG_APPLOCAL_DEPS_INSTALL`.

However, current `vcpkg` introduces a limitation if one does that:
While it is totally cool with CMake to specify multiple targets within
one invocation of `install(TARGETS ...) (at least according to
https://cmake.org/cmake/help/latest/command/install.html#command:install),
`vcpkg`'s parser insists on a single target per `install(TARGETS ...)`
invocation.

Well, that's easily accomplished: Let's feed the targets individually to
the `install(TARGETS ...)` function in a `foreach()` look.

This also has the advantage that we do not have to manually cull off the
two entries from the `${PROGRAMS_BUILT}` array before scheduling the
remainder to be installed into `libexec/git-core`. Instead, we iterate
through the array and decide for each entry where it wants to go.
