kmod-lzo: include the lzo-rle kmod in the package

kmod-lzo: include the lzo-rle kmod in the package

Albeit a separate crypto module, lzo-rle uses the same kernel library as lzo.
Crypto API users (zram, for example) expect both lzo and lzo-rle to be
available, so let's include lzo-rle (about 5.5 kiB) in the lib-lzo package.
