pseudo: force NO32LIB to true for nativesdk

The exported SDK only needs simulated root privileges for specific
tasks, such as the user-mode NFS server or rootfs extraction, and
oe-core does not support multilib builds in the generated SDK, so
it is neither necessary nor possible to build a 32-bit libpseudo.so
for a 64-bit SDK.
