_PC_CHOWN_RESTRICTED can only be used via pathconf/fpathconf not sysconf

[BernardQuatermass]

The documentation regarding availability of chown (perldoc -f chown) incorrectly uses the sysconf() function rather than the pathconf() function along with a path.

PC* can only be used as parameters to pathconf()/fpathconf(). Only SC* values can be used against sysconf().

Cannot speak to other systems but on all linux systems the original code would be returning the value for "_SC_TZNAME_MAX, The maximum number of bytes in a timezone name."

There is also an matching misuse in cpan/File-Temp/lib/File/Temp.pm

The modules in cpan/ are maintained elsewhere (see Perl-Toolchain-Gang/File-Temp#41). The change to File::Temp should be reverted.

The change to perlfunc.pod looks good to me.

Yes, there should be no change to File::Temp in this p.r.; that should be done upstream.

@BernardQuatermass, can you run perl Porting/updateAUTHORS.pl to add your name and email address to our AUTHORS file, then re-push? thanks.
