linker: Allow caller to specify parent namespace

This change enables apps to share libraries opened
with RTLD_GLOBAL between different classloader namespaces.

The new parameter to create_namespace allows native_loader
to instruct the linker to share libraries belonging to
global group from a specified namespace instead of
using the caller_ns.
