Add unlink support to moxie simulator
This change adds support for the unlink system call, which is
required by the GCC testsuite. It also switches read/write/open
system calls to use the sim_io_* functions.

* interp.c (sim_engine_run): Make use of sim_io_* functions for
read/write/open system calls. Implement the unlink system call.
