Thomas Haller 6c90b529a1 build: fix make always re-making vapigen target
Reproduce:

  make
  touch libnm-util/NetworkManager-1.0.gir
  make
  make
  # rebuilds "VAPIGEN vapi/libnm-util.vapi" every time.

  ls -la libnm-util/NetworkManager-1.0.gir vapi/libnm-util.vapi
  # note that vapi/libnm-util.vapi was not touched.
