From O, libutils.so is loaded twice. Once in the default namespace and
once in the sphal namespace for vendor libs. However, since the
framework only communicates with the instance loaded in the default
namespace, report_sysprop_change() event is not notified to the instance
in sphal namespace. This causes ATRACE to not work for vendor libs
loaded in sphal namespace.
So, the instance loaded in default namespace now explicitly redirects
the event to the other instance.
Bug: 62084107
Test: start an app, run 'adb shell atrace gfx --stream'. atrace from the
graphics driver are visible.

Instead of looking up default namespace for the failure of loading
sphal libs, report failure. This is only for the devices that have
sphal namespace.

libvndksupport is a new LL-NDK library that provides vendor-visible APIs
for platform-only functionalities of other LL-NDK libraries. Currently,
it provides android_(load|unload)_sphal_library which abstracts the
platform-only APIs of libdl (android_get_exported_namespace, etc.)
