gpu: nvgpu: unit: copy largest libraries last

Browse Source 
For some units that depend on libraries, tmake generates
what seems to be stub libraries, with all functions
implemented as a simple 'ret' instruction.

For instance, libfalcon_utf.so can be seen in multiple places:
du -b $(sudo find . -name libfalcon_utf.so)
7808	./nvidia/kernel/nvgpu/userspace/units/pmu-l4t_64/libfalcon_utf.so
7808	./nvidia/kernel/nvgpu/userspace/units/acr-l4t_64/libfalcon_utf.so
7808	./nvidia/kernel/nvgpu/userspace/units/falcon/falcon_tests-l4t_64/libfalcon_utf.so
76968	./nvidia/kernel/nvgpu/userspace/units/falcon-l4t_64/libfalcon_utf.so
76968	./systemimage/home/nvgpu_unit/units/libfalcon_utf.so

The "real" library is in falcon-l4t_64/, and it contains actual code.

But install-unit.sh copies all *.so files to nvgpu_unit/units on target.
In some cases, we end up with a "stub" library being used instead of
the expected one.

To avoid this, make sure to copy the largest libraries (in bytes) last.
Also, remove the '-u' option of rsync to force the copy.
