File::Temp::HIGH relies on a bogus _PC_CHOWN_RESTRICTED check

[veprbl]

This logic shoves a flag from pathconf() into sysconf(), allegedly, to check the value of _POSIX_CHOWN_RESTRICTED:

File-Temp/lib/File/Temp.pm

Lines 745 to 752 in 2847f33

	$chown_restricted = &POSIX::_PC_CHOWN_RESTRICTED()
	if eval { &POSIX::_PC_CHOWN_RESTRICTED(); 1};
	# If chown_resticted is set to some value we should test it
	if (defined $chown_restricted) {
	# Return if the current directory is safe
	return _is_safe($path,$err_ref) if POSIX::sysconf( $chown_restricted );

Apparently what happens in reality is a call to sysconf(_SC_TZNAME_MAX).
