    libacpi: fixes for iasl >= 20180427
    
    New versions of iasl have introduced improved C file generation, as
    reported in the changelog:
    
    iASL: Enhanced the -tc option (which creates an AML hex file in C,
    suitable for import into a firmware project):
      1) Create a unique name for the table, to simplify use of multiple
    SSDTs.
      2) Add a protection #ifdef in the file, similar to a .h header file.
    
    The net effect of that on generated files is:
    
    -unsigned char AmlCode[] =
    +#ifndef __SSDT_S4_HEX__
    +#define __SSDT_S4_HEX__
    +
    +unsigned char ssdt_s4_aml_code[] =
    
    The above example is from ssdt_s4.asl.
    
    Fix the build with newer versions of iasl by stripping the '_aml_code'
    suffix from the variable name on generated files.
