Azat Khuzhin 89c071e291 Build rust modules from the binary directory
Our crates has configuration files:
- config for cargo (see config.toml.in)
- and possibly config for build (build.rs.in)

Previously it uses source directory, and it will overrides files in the
source directory, which will require recompile of crates in case of
multiple builds for one source directory.

To avoid overlaps different builds for one source directory, crate will
be copied from source directory to the binary directory.
