    image_types: Add support to compress initramfs with lz4
    
    Changed to use lz4 as lz4c seems to be deprecated.
    
    Removed use of redirection in favor of using output file.
    
    As Linux kernel supports only legacy format for initial ramdisk add
    COMPRESS_CMD_lz4_legacy mode in case some users are using newer format.
