pmdomain: core: Fix "managed by" alignment in debug summary

The "performance" column contains variable-width values.  Hence when
their printed values contain more than one digit, all values in
successive columns become misaligned.

Fix this by formatting it as a fixed-width field.  Adjust successive
spaces and field widths to retain the exiting layout.
