Bugtool: Fix format in dump files.
Bugtool: Fix format in dump files.

Nowadays each time that a % is present in the command output, the print
will be invalid and can't be read easily.

Example invalid output:

```
PID USER      PR  NI    VIRT    RES    SHR S  %!C(MISSING)PU %!M(MISSING)EM     TIME+ COMMAND
```

With this change the output will be the original one:

```
  PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND
```
