Fixed image size

[Dashboy1998]

Context

• Reduces image size
• Also delete /tmp/dumps to remove this error when starting as nonroot and a user which does not have a UID of 1000 /tmp/dumps is not owned by us - delete and recreate

Choices

Previously we changed the permission of /home/steam/steamcmd/ which resulted in an image size increase of 300MB. Now making the directory we need and changing it's permission

Test instructions

1. Test that is runs with the default compose
2. Test as user 1000:1000
3. Test as any other user

Hi @Dashboy1998 Thanks for making this so quick, however I don't see a size difference:
