    x86: remove old lzma tuning patch
    
    Chen Minqiang reported in his GitHub PR #4733 that:
    With CONFIG_TARGET_INITRAMFS_COMPRESSION_LZMA=y option set,
    the popular x86/amd64 target's initramfs-kernel failed to boot.
    
    The cause for this boot failure is that the LZMA compression
    uses a the first bytes to encode the compression parameters.
    It does not have a fixed magic. Yes, this only works if the
    the existing lzma options in the upstream are not changed.
    
    This patch does away with OpenWrt special LZMA options tuning
    since it is rather unlikely that upstream will improve the
    compression algorithm detection after all this time. Even
    though, the tuning produced a smaller initramfs (~1.1% in a
    spot check).
