btrfs-progs: tests: add Makefile for testsuite

Add a Makefile so tests can be run the same way from the standalone
testsuite as they are from git. The build dependencies are not checked
and the default path is for the system binaries.

Because of the path auto detection, running 'make' from the tests/
directory now works the same way as from the toplevel git directory.
