phosphor: Include perf and trace-cmd in tools-profile

When this .bbappend was added, it had the following commit message:

    Add tools-profile feature support

    With this patch, the build system supports the tools-profile feature,
    We can add it into the EXTRA_IMAGE_FEATURES in conf/local.conf,
    to add more debug/profile tools into the image

It is desirable to have perf and trace-cmd in the image when pulling in
debug tools, so remove the removal.
