The helper function we use for signal name mapping does not
check for negative numbers nor invalid (too-high) ones. This
can yield unexpected error messages:
# podman kill -s -1 foo
ERRO[0000] unknown signal "18446744073709551615"
This PR introduces a small wrapper for it that:
1) Strips off a leading dash, allowing '-1' or '-HUP'
as valid inputs; and
2) Rejects numbers <1 or >64 (SIGRTMAX)
Also adds a test suite checking signal handling as well as
ensuring that invalid signals are rejected by the command line.
Fixes: #4746
