Fix analyze-profile phase summary format

The current output of `bazel analyze-profile ...` is not properly formatted and looks like:
```
=== PHASE SUMMARY INFORMATION ===

Total launch phase time         1.486 s    0.51%
Total init phase time           0.422 s    0.15%
Total target pattern evaluation phase time    6.203 s    2.15%
Total interleaved loading-and-analysis phase time  100.341 s   34.71%
Total preparation phase time    0.376 s    0.13%
Total execution phase time    180.205 s   62.33%
Total finish phase time         0.086 s    0.03%
------------------------------------------------
Total run time                289.121 s  100.00%
```

this fixes it to:
```
