fmemopen.3, getaddrinfo.3, mq_notify.3, offsetof.3, aio.7: Print size_t/ssize_t values using %z printf() modifier

There are fewer and fewer systems these days that don't
support the %z specifier mandated in C99.  So replace the
use of %ld/%lu + (long) cast with %zd/%zu.

netlink.7: ffix: Remove unneeded .na / .ad tags

These aren't really needed, and they mess up the HTML pages
at man7.org.

rtnetlink.7: ffix: Remove unneeded .na / .ad tags

The result without these tags looks acceptable.
With these tags, the HTML rendering on man7.org
is bit messed up.
