Make ping6(1) return code consistent with the man page.

Browse Source 
When every sendto() call originated by ping6(1) fails, current code always
 returns 2 ("transmission was successful but no responses were received")
 which is incorrect. Return EX_OSERR instead as in many cases it indicates
 some kernel-level problems.
