pkg/cover, syz-manager: show coverage summary

* pkg/cover, syz-manager: show coverage summary

The funccover or cover page is not easy for statistic purpose.

So add /cover?type=rawfiles to show coverage based on each file.
And /cover?type=table page to show coverage for group of components.

If driver_path_map.json exists, /cover?type=table can show component coverage.
Format example:
    {
      "all": [ "/" ],
      "audio": [
        "/techpack/audio/asoc",
        "/techpack/audio/dsp",
        "/techpack/audio/ipc",
        "/sound/core"
      ]
    }

If driver_path_map.json not exist, it will show one line summary.

* pkg/cover: use subsystem naming

* syz-manager: use /subsystemcover and /filecover

* pkg/cover: use subsystem from config

* pkg/mgrconfig: add kernel_subsystem

* pkg/cover, tools/syz-cover: fix make test

* all: fix presumit errors

* pkg/cover, syz-manager: fix subsystem
