qemu-option: Make qemu_opts_foreach() accumulate return values

Browse source 
Return the bitwise inclusive or of all return values instead of the
last call's value.  This lets you find out whether any of the calls
returned a non-zero value.

No functional change, as existing users either don't care for the
value, or pass non-zero abort_on_failure, which breaks the loop on the
first non-zero return value.
