check-bin-arch: skip /lib/modules to allow 32-bit userland on 64-bit arch
The script check-bin-arch fails as follows on a config for PowerPC e6500 (64-bit CPU) with BR2_ARCH="powerpc" (32-bit userland desired): ERROR: architecture for "/lib/modules/..../lib/libcrc32c.ko" is "PowerPC64", should be "PowerPC" This situation is perfectly acceptable: the kernel is 64-bit and so are its modules, even though userland is 32-bit. To keep check-bin-arch and its caller simple, just skip /lib/modules/ entirely, like is done for /lib/firmware and some others.
