[CRIU] [PATCH v3] Makefiles: add install target

[Kir Kolyshkin]

Note to package maintainers:

1 Yes we do support DESTDIR.

2 From packaging scripts, use something like this:

	make install DESTDIR=$RPM_BUILD_ROOT PREFIX=/usr

(v2: add PREFIX, install to /usr/local not /usr by default)
(v3: fix criu man section -- it is 8 not 1)
