Revert "[uefi] enable 32bit uefi support"

This reverts commit 2c7735709d948bf28391023c99ab08e39a7917e7.

it did not work. thanks to t-nelson for testing it..

1. Zotac ZBOX PI320 pico wants bootia32.efi not bootx32.efi
2. even with bootia32.efi (from syslinux) it doesnt boot. I suspect it requires pure 32bit kernel. no mixed mode ?

thank you zotac for creating such a mess.. damn it's almost y2k15
projects/*/linux: Enable Netfilter owner matching, this fixes #3607, this fixes #3585
