Bug#472551: gnome-applets-data *requires* mktemp for postinst

[Tom Parker]

Package: gnome-applets-data
Version:2.22.0-1

Didn't have mktemp installed, and I got the following while trying to
install gnome-applets-data

Setting up gnome-applets-data (2.22.0-1) ...
Installing new version of config file
/etc/sound/events/battstat_applet.soundlist ...
/var/lib/dpkg/info/gnome-applets-data.postinst: 30: mktemp: not found
dpkg: error processing gnome-applets-data (--configure):
 subprocess post-installation script returned error exit status 127

mktemp is 'Required' not 'Essential' so AFAIK gnome-applets-data needs
to declare dependencies on it.
