Prevent unnecessary rebuilding of libs.

- When building for Rockbox Utility the called Makefiles would rebuild the libs
  every time. Change dependencies a bit to allow make to properly detect if the
  lib is already up to date.
- Remove dependency on output folder in some cases to avoid unnecessary
  rebuilds.
- Add standard Rockbox header to files lacking it.
- Make make calls from qmake silent.
