Subject: [PATCH 1/2] test help output during normal option parsing

The existing test for "fping -h" triggers the special code path
for only one option, either -h or --help, that is handled before
normal option parsing.

Subject: [PATCH 2/2] test error when binding to wrong local address

Test "fping -S" with both IPv4 and IPv6 addresses not configured
on local interfaces using addresses reserved for documentation.
Check the fping error message, but accept any system generated
additional information.  This additional information differs
between operation systems.
