[ARITH] Fix logical or result value
Another change I'm making to the arith code is making || return 0 or 1
only, matching C, POSIX and other shells.

Apart from the compliance issue, it is also bad to expose implementation
details like the exact meaning of 'noeval' to scripts such that they may
come to depend on them.
