"Tools" in the context of a binary name doesn't make any sense,
because every binary is a tool (lstool, dftool), plus it's one
tool.
So let's rename the beast to criu, which is short, pretty unique
and coincides with the name of the project.
Backward-compatible symlink is added for the sake of tests,
we can fix them later and remove the link.
Packagers beware: our binary is no longer crtools but criu.
