Update CMake find module for LZ4

# Finds liblz4.

#

# This module defines:

# LZ4_FOUND

# LZ4_INCLUDE_DIR

# LZ4_LIBRARY

# - Find Lz4

# Find the lz4 compression library and includes

#

# LZ4_INCLUDE_DIR - where to find lz4.h, etc.

# LZ4_LIBRARIES - List of libraries when using lz4.

# LZ4_FOUND - True if lz4 found.
