test/system: Fix ulimit tests on Ubuntu host

[petraglyph]

ulimit is a shell builtin, so the shell it is run from changes the version that is used. Ubuntu (and Debian) use dash as their system shell, instead of bash. The means that toolbox run also used dash with Ubuntu containers, caused an unexpected version of ulimit to be used in tests. Tests were updated to force the use of bash and its version of ulimit.

We should add test/system/210-ulimit.bats to .github/workflows/ubuntu-tests.yaml to enable them in the CI.

I took the liberty to do this, and rebased on top of main. The commit message still needs fixing.

I took the liberty to update the commit message.

I didn't want to delay this any further because of relatively minor details.
