Transition from "JIRI_ROOT/devtools/bin" to "JIRI_ROOT/.jiri_root/scripts".

We are removing support for the "devtools/bin" directory.  Binaries are
installed in to JIRI_ROOT/.jiri_root/bin.  (Currently, devtools/bin is
just a symlink to .jiri_root/bin.)

Users should have JIRI_ROOT/.jiri_root/scripts in their path.  The jiri
script lives in that directory.
