[CRIU] [PATCH 00/24] More polishing for compel cli

[Kir Kolyshkin]

The aim of these patches is to improve compel cli usability.

1. To use compel,  one has to specify paths to compel tool itself,
to compel headers, to compel lib, and to compel plugins.
With this patchset, only the binary path is needed (and only
if compel is not installed, or installed in a non-standard path),
and the rest of information can be obtained from compel itself.

2. It appears that --arch option is not needed, as compel can only
be compiled for a specific architecture. Instead, --compat is
introduced to be used for 32-bit mode on x86 (maybe --compat
can also be dropped later, I still haven't figured it out).

3. As I worked with Makefiles, I made some changes, hopefully
to make them easier to work with.

4. Some minor stuff here and there.

Dmitry, Cyrill, please review.
