PFW: Enhance subsytem libraries load mechanism

BZ: 24093

If a subsystem library depends on another one, the libraries have to be loaded
in a predefined order.

the previous recovery mechanism on PFW was: When a subsystem library does not
load because of a missing dependency, it tries to load all the other subsystems
before trying one more time to load the failing library.

Unfortunately, Android linker does not allow several try when loading a
library.

In consequence, this patch implements a new mechanism to load its subsystem
libraries.
For this new mechanism, the PFW will load the subsystem libraries in the order
they are disposed in the file ParameterFrameworkConfiguration.xml
