This reverts commit 484fd6c1de13b336806a967908a927cc0356e312.  The
commit caused a regression because now the umask was applied to
symlinks and the fix is unnecessary because the umask/O_TMPFILE bug
has been fixed somewhere else already.

Fixes: https://lore.kernel.org/lkml/28DSITL9912E1.2LSZUVTGTO52Q@mforney.org/

Thanks, Max! I've verified that this fixes symlink modes for me,
as well as the flatpak corruption error I was getting.

Just checking in on this. I'd really like to see this regression
fixed. It currently affects versions 6.5 through 6.9-rc6 as well
as all longterm releases.
