unix.7: Update text on socket permissions on other systems
At least some of the modern BSDs seem to check for write
permission on a socket. (I tested OpenBSD 5.9.) On Solaris 10,
some light testing suggested that write permission is still
not checked on that system.
See https://bugzilla.kernel.org/show_bug.cgi?id=120061 (and
https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-1999-1402)
