To remove the first line containing file name and file format as below,

    $ objdump -l -d -S -C /home/taeung/a.out | head -2

    /home/taeung/a.out:     file format elf64-x86-64

currently perf-annotate use objdump with grep -v "file name".
But it cause a side effect eliminating filename:linenr of
output of 'objdump -l' so fix it.
