Allow temp_make and temp_del to be run in setup_file and teardown_file

Fixes #35

[NickLarsenNZ]

I'm just adding tests now

I've just followed the existing pattern, but might need someone more familiar with bats-file to take a closer look.
Also, looks like the tests fail for reasons mentioned in #31

@NickLarsenNZ I would love this fix, do you think you could get the CI build passing?

[NickLarsenNZ]

Hi @jlisee, I took a look at the issue I linked above and it is still open and unresolved.

When I'm at my laptop I'll rebase and check. Maybe I'll look at the cause of the test failures and try to resolve the other ticket before progressing this one.

I had a quick look at the existing CI issues and I wonder if it's a problem with batslib_is_caller from over in https://github.com/bats-core/bats-support.

Maybe @sublimino might know?
Maybe in the meantime those failing tests can be skipped so PRs can progress. In saying that, it looks like there's not a lot of movement on this repo judging by the length of time the open PRs have been sitting here.

I rebased onto current master to get the CI fixes in.
