gpu: nvgpu: remove RTLD_GLOBAL flag from libnvgpu-drv.so dlopen for QNX tests

Browse Source 
currently libnvgpu-drv.so is opened with RTLD_GLOBAL flag which is
required for nvgpu common tests but for qnx tests we dont need any
symbol from libnvgpu-drv.so (except nvgpu_posix_probe and
nvgpu_posix_cleanup which we will eventually remove for qnx) so
RTLD_GLOBAL should not be used in case of qnx tests. If RTLD_GLOBAL is
used for qnx tests then the symbols from libnvgpu-drv.so will be used
instead of from libqnx_mock.so which is wrong.

This change uses -Q command line option to make the decision about
RTLD_GLOBAL flag

After this change qnx unit tests should be run with -Q option and nvgpu
common unit tests should be run without it
