tests: simplify invalid signal determination for kill -l
* src/operand2sig.c (operand2sig): Add a detailed comment explaining
why we validate even very large shell exit status values.
* tests/misc/kill.sh: Add a test case for the ksh scheme.
Simplify the INVALID signal number determination which also avoids
a false failure on systems like FreeBSD 10 with incomplete
signal list (caused by inaccurate NSIG).
