[LibOS/shim/test] Copy Makefile to Makefile.Test and use it

LibOS/shim/test/Makefile has confusion. It's makefile for test/ directory
and common functions for each test directory.
As a first step to untangle the confusion, copy Makefile.Test for
common functions and have test directories to use it.
Later once grapene-tests is updated, LibOS/shim/test/Makefile
will have only submake rules.
