Bug#226235: xserver-common: Should not re-create /etc/X11/Xwrapper.config in /tmp

[Russell Coker <russell@coker.com.au>]

Package: xserver-common
Version: 4.2.1-15
Severity: normal

Currently the postinst creates a temporary file in /tmp for the new Xwrapper.config.  There is no benefit in doing this,
it might as well use $XWRAPPER_CONFIG.dpkg-new all along with no loss of functionality.

For SE Linux a file created in /tmp gets a different context, and if it is moved to /etc and /etc and /tmp are in the
same file system then it retains a type that prevents most domains from accessing it.
