Add perf to the linuxkit distro

[tekumara]

I'd like to performance debug containers running on docker for mac.

Would it be possible to ship perf with the linuxkit distro that comes with docker for mac?

Expected behavior

perf is shipped with docker for mac and so can be run via screen (or when entering pid 1)

Actual behavior

perf isn't currently part of the docker for mac distribution

Information

• macOS Version: 10.14.6 (18G1012)

Diagnostic logs

Docker for Mac: version... 2.1.0.5 (40693) 
Engine: 19.03.5
Machine: 0.16.2

Linux docker-desktop 4.9.184-linuxkit #1 SMP Tue Jul 2 22:58:16 UTC 2019 x86_64 Linux

Steps to reproduce the behavior

screen ~/Library/Containers/com.docker.docker/Data/vms/0/tty
/ # perf
/bin/sh: perf: not found

Could you please retest in Docker Desktop 2.5? As of 2.5, we are up to date with upstream LinuxKit, so any missing modules should be requested in the https://github.com/linuxkit/linuxkit repo.

I'm also interested in using perf in a container on macOS. According to https://github.com/linuxkit/linuxkit/blob/master/docs/kernel-perf.md perf should be functional in linuxkit kernels, but within the container corresponding user-space tools have to be installed. In case of Ubuntu 20.04, perf tells me:

root@mongooseim-1:/# perf
WARNING: perf not found for kernel 5.4.39

  You may need to install the following packages for this specific kernel:
    linux-tools-5.4.39-linuxkit
    linux-cloud-tools-5.4.39-linuxkit

  You may also want to install one of the following packages to keep up to date:
    linux-tools-linuxkit
    linux-cloud-tools-linuxkit

But there's, obviously, no linux-tools-5.4.39-linuxkit in Ubuntu upstream repositories. How do I get the correct perf version for a linuxkit kernel (ideally for Ubuntu 20.04)?
