fix permissions on /run/php so php-fpm can run, fixes #20

[rfay]

The Issue

• Failing with DDEV HEAD due to permissions on /run/php #20

Something about the Dockerfile for this has set /run/php permissions differently.
Moving this to pre.Dockerfile seems to solve the problem, but we still have to chmod the /run/php in the Dockerfile.

Release/Deployment Notes

• Testing of the release has been remove temporarily, so needs to be re-enabled after this is in a release.

I think this will work, but requires a release, or the release build fails on HEAD.

Sorry @rfay, when you write

Try to work with DDEV HEAD

to test it manually, could you give me instructions to do it?
I would test this PR locally, but I don't remember how to do it. ;(

You bet, see https://ddev.readthedocs.io/en/latest/developers/building-contributing/#testing-latest-commits-on-head

Thanks for maintaining this!

[robertoperuzzo]

Tested locally and it is fine. I'm going to merge it and then I re-enable the release test.

I will open a new issue to update the pre.Dockerfile.sqlsrv to Debian 12; probably it will fix the permission on /run/php

This will need a release to get tests green, thanks!
