build: Link subprojects statically if built as a subproject

If we're building a dependency as a fallback subproject, we don't want
to be responsible for installing it as a shared library. Anyone wanting
shared libraries should install the dependencies separately.

Ideally we'd do this with MSVC too, but that doesn't currently link
successfully (dbus#549).
