Subject: Fix wrong permissions on pacnew extraction

First reported here:
http://bbs.archlinux.org/viewtopic.php?pid=261861

Newly created files were done with the standard umask, so those that are
extracted seperately and copied to a .pacnew extension will have the wrong
permissions. This should hopefully fix this.
