    libxc: remove broken endianess gate on lz4 decompressor
    
    The lz4 decompressor had wrongly implemented a gate between
    little-endian and big-endian versions of get_unaligned_le{16/32},
    which turns out to be broken on all architectures supported by Xen,
    because __LITTLE_ENDIAN is not defined. Instead of trying to fix
    this, just implement the little-endian version and remove the switch.
