[CRIU] [PATCH 0/6 v2] build/make fixes

[Cyrill Gorcunov]

v2: Dropped patch for "dropping feature-test.mak dependency"
    Reworded and describe patches fuller.

Mostly - dropping unneeded and simplifying makefiles.
Another little thing -- build everything from a top directory,
which will allow things like `make criu/log.o`, jumping from
vim to build error and etc.

There are some refactoring left to do, but at least, everything
looks working quite good.
