[PATCH] Fix <get-attachment> to use $tmpdraftdir.

I missed converting it before because it was hidden inside a shared
function, mutt_rfc1524_expand_filename().  Most of those callers use
the file for an actual $tmpdir file, but <get-attachment> should put
it in the compose $tmpdraftdir like other attachments.

Add a parameter to select the $tmpdraftdir and modify
mutt_get_tmp_attachment() to set the parameter when calling.
