[CRIU] [PATCH] make install: guess LIBDIR

[Kir Kolyshkin]

For x86_64, LIBDIR can be tricky to find out. Nevertheless, this
works for at least RedHat/CentOS/Fedora, SLES/openSUSE, Debian/Ubuntu
and Gentoo. So, while it can guess LIBDIR wrong, this is still
a good approximation for those installing criu from source.
