lxc: fixup 'download' template use

We have a new dependency on 'mountpoint' which is now called in the
download template script. We also hit an upstream bug due to improper
use of 'mktemp', so we apply a patch to fix this and sent the fix
upstream as well.

+Subject: [PATCH] templates: actually create DOWNLOAD_TEMP directory
+
+The way 'mktemp' is currently used you will get a temp directory in
+$TMPDIR or '/tmp' and DOWNLOAD_TEMP will not be pointing to an actual
+directory. This will result in the wget operations failing and the
+container will fail to create:
+
+    ERROR: Failed to download http://....
+
+Instead we want to use the '-p' option for mktemp to set the base path
+and this will ensure that the temp directory is created in the correct
+location and DOWNLOAD_TEMP will be consistent with this location.
+
+Upstream-Status: Pending
