Subject: [PATCH] Makefile: Micropolis build fixes for recent macOS

Hide the sim executable in an appropriately-named subdirectory of libexec
rather than directly in libexec.

In the micropolis wrapper script, use a shebang line, use exec so that the
shell doesn't stay around, and quote user-supplied arguments properly.
