perf tools: Align long options which have no short forms

Before:

$ ./perf kmem
...
    -l, --line <num>      show n lines
    --raw-ip              show raw ip instead of symbol

After:

$ ./perf kmem
...
    -l, --line <num>      show n lines
        --raw-ip          show raw ip instead of symbol
