[oe] [meta-networking][PATCH] ebtables: enable KERNEL_64_USERSPACE_32 for arm

[Li Zhou]

On arm64 board, run the kernel as 64bit with 32bit userpace ebtables,
then run ebtables command:
ebtables -A OUTPUT -p arp -o eth3 -j DROP
Below error occurs:
kernel msg: ebtables bug: please report to author: Standard target size too big

To solve this, enable KERNEL_64_USERSPACE_32 for arm as the commit
<ebtables: enable KERNEL_64_USERSPACE_32 for powerpc> do.

Use TARGET_ARCH to replace KARCH here because that KARCH can't always get
value by default.
