Add amount of disk space used by build to the log

[sxa]

This will help log information that we can give to end users to tell how much space is required for builds, and also help with capacity planning on machines

Looks like TKG is broken - unrelated

LGTM

FYI to reviewers the new push is to fix quoting which was a mess so hopefully doesn't affect you're review :-)

@sxa not sure why the checks are all failing..

[sxa]

See separate new issue referenced above for the GitHub check problems.

Switching this to draft just now becuase it's not working. When I run make-adopt-build-farm it gets to the end of build.sh and then stops after build.sh : 09:56:13 : All done! so it's not falling back to this script - maybe the result of an exec somewhere? Another commit will be required for this to work as expected (Or it could potentially be moved into build.sh however it's more for our infrastructure's benefit so this feels like the right place for it)

Rebasing to see if any of the actions failures fix themselves ...

only the gpg failure on centos7

There are still a few issues in this area which I believe others are covering at the moment. On the basis that this PR is (hopefully clearly) not the cause of them I'm happy to merge this with those checks failing.

This was user error on my part as I hadn't set the WORKSPACE directory before running my local test. It is working as expected. IMHO this is good to merge (@andrew-m-leonard if you're ok to approve given my earlier response to you that would be appreciated.

@andrew-m-leonard I'm going to merge this now since it has two approvers and your suggestions do not conflict with this. We can do a subsequent PR if you want to add the df somewhere.
