lib/lz4/ has never had one: get_maintainer.pl returns only the LKML
fallback for every file in it, including include/linux/lz4.h, which eight
subsystems build against.

The entry also takes lib/decompress_unlz4.c and its header, which
decode LZ4 kernel images and initramfs through lib/lz4, the way XZ
EMBEDDED covers its own equivalents, and crypto/lz4.c and crypto/lz4hc.c,
the crypto API wrappers zswap uses, as ZSTD takes crypto/zstd.c.

This matters more now than it did. With the previous patches lib/lz4 is
vendored upstream sources, and someone has to bump them to new upstream
releases and decide what the kernel-side glue may do. I am willing to do
that, so add myself as its maintainer.
