zram: break the strict dependency from lzo
From the beginning, the zram block device always enabled CRYPTO_LZO,
since lzo-rle is hardcoded as the fallback compression algorithm. As a
consequence, on systems where another compression algorithm is chosen
(e.g. CRYPTO_ZSTD), the lzo kernel module becomes unused, while still
having to be built/loaded.
This patch removes the hardcoded lzo-rle dependency and allows the user
to select the default compression algorithm for zram at build time. The
previous behaviour is kept, as the default algorithm is still lzo-rle.
