Fix errors with sys::execve on linux

A fix for #641

writeln!(stderr, ...) -> eprintln!

Add the exec builtin

While working in other tasks, I noticed that there's a rather
inconsistent way to handle errors. In some places we use `eprintln!` and
in others `writeln!` to standard error.

It seems like the use of `writeln!` don't have an strong motive, as the
output is always to standard error, the lock is always handled the same
than `eprintln` and there's no obvious (to me) optimization, so I
decided to use the more idiomatic `eprintln!` everywhere.

 - Add the necessary functions to builtin
 - Add the necessary interfaces for the execve syscall
   - Add sys::unix::execve
   - Add sys::redox::execve

This fix will ensure that comments within multi-line array assignments are properly
handled within both the REPL and script executions.

Closes #642

To enable this option, use `set -o huponexit`. This will send **SIGHUP** to all background jobs when
exiting the shell. If a background job is stopped, that job will be resumed with a **SIGCONT**
before being sent a **SIGHUP**.
