linux-user: Fix broken "-version" option
Fix the "-version" option, which was accidentally broken in commit fc9c541: * exit after printing version information rather than proceeding blithely onward (and likely printing the full usage message) * correct the cut-n-paste error in the usage message for it * don't insist on the presence of a following argument for options which don't take an argument (this was preventing 'qemu-arm -version' from working) * remove a spurious argc check from the beginning of main() which meant 'QEMU_VERSION=1 qemu-arm' didn't work.
