remove rand crate

the few uses of rand::thread_rng() have been replaced with either
prngs or reads from /dev/urandom. the implementations are under
the `rand_ish` minicrate.

`protoc-rust` depends on `tempdir`, which relies on rand, so
`tempdir` has been patched with a rewritten version that does not
have rand as a dependency.
