PATCH: 3.1.6-pws-2: cap_free

[Peter Stephenson <pws@xxxxxxxxxxxxxxxxx>]

I've finally compiled on a system with POSIX capability sets.  This one
definitely needs cap_free to get the value returned from cap_get_proc, not
a pointer to it.  If there are implementations which do this the other way,
we have problems.

You can test this if you also have --enable-zsh-mem --enable-zsh-mem-debug,
because you get a bad free warning from e.g. `print -P "%#"'.
