Add a rustc option to strip environment information from path strings 

Usernames and other environment specific information can be revealed
in on-chain program binary files that compiler generates, because it
includes paths to source files as strings in the binary files.  The
added option instructs the compiler to strip the path parts up to
and including crate root subdirectory from the path strings added to
the generated binary files.
