devtools: restore null test

Browse Source 
This small testpmd test was not working for a long time
because of several changes in EAL and mempool.
The 3 main issues solved are:
	- Make --no-huge working by specifying an amount of memory
		to allocate in legacy mode, and disabling mlockall.
	- Load a mempool handler in shared library case.
	- Support meson
