There were a few issues that were causing qemu-system-arm and
qemu-system-riscv to give the wrong exit codes. They are in fact capable
of exiting with 0 or 1 signalled from the running application, but this
functionality wasn't used. This commit changes this in the following
ways:
* It fixes SemiHosting codes, which were incorrectly written in
decimal while they should have been written in hexadecimal (oops!).
* It modifies all the baremetal main functions (aka reset handlers) to
exit with `exit(0)` instead of `abort()`.
* It changes `syscall.Exit` to call `exit(code)` instead of `abort()`
on baremetal targets.
* It adds these new exit functions where necessary, implemented in a
way that signals the correct exit status if running under QEMU.
All in all, this means that `tinygo test` doesn't have to look at the
output of a test to determine the outcome. It can simply look at the
exit code.
