kamil 7806b47917 Rework perform_arith_op() in expr(1) to omit Undefined Behavior 
The current implementation of operations - + * / % could cause Undefined
Behavior and in narrow cases (INT64_MIN / -1 and INT64_MIN % -1) SIGFPE
and crash duping core.

Detected with MKSANITIZER enabled for the Undefined Behavior variation:
# eval expr '4611686018427387904 + 4611686018427387904'
/public/src.git/bin/expr/expr.y:315:12: runtime error: signed integer overflow: 4611686018427387904 + 4611686018427387904 cannot be represented in type 'long'

All bin/t_expr ATF tests pass now in a sanitized userland.
