Revert "sandbox: remove os_putc() and os_puts()"

While sandbox works OK without the special-case code, it does result in
console output being stored in the pre-console buffer while sandbox starts
up. If there is a crash or a problem then there is no indication of what
is going on.

For ease of debugging it seems better to revert this change.

This reverts commit 47b98ad0f6779485d0f0c14f337c3eece273eb54.
