[PATCH] Remove ext4 support from the packaging defconfig

[W.Kenworthy]

I raised a bug some time ago to get reiserfs3 turned on in the kernel -
specifically to handle tangogps map files which ext2/3 dons not do well
(space and performance issues).

Its obviously not thought important enough - is there any likely hood of
it ever happening?
