tests/tcg: fix semihosting SYS_EXIT for aarch64 in boot.S

Browse source 
We don't expect to hit exceptions in our testing so currently all the
vectors report an un-expected exception and then attempt to exit.
However for aarch64 we should always use the extended information
block as we do in _exit. Rather than duplicate the code on the error
handler just branch to the _exit handler with a failing status code.
