commit f527e4f2c66f078ca169f4847034150ec1b02d11

    Replace file path by a fixed placeholder in readelf and objdump output
    
    We used to replace the file path by its basename. But this won't work when
    diffoscope is working on two ELF files with different basename (which can
    easily happen when the command line specify two different ELF files).
