CI failing when launching TestWasm with wasmbrowsertest

[igolaizola]

The CI is currently failing with this error when trying to launch TestWasm with wasmbrowsertest:

No usable sandbox! If you are running on Ubuntu 23.10+ or another Linux distro that has disabled unprivileged user namespaces with AppArmor, see https://chromium.googlesource.com/chromium/src/+/main/docs/security/apparmor-userns-restrictions.md. Otherwise see https://chromium.googlesource.com/chromium/src/+/main/docs/linux/suid_sandbox_development.md for more information on developing with the (older) SUID sandbox. If you want to live dangerously and need an immediate workaround, you can try using --no-sandbox.

I have 2 proposals to fix this:

Disable AppArmor

Check this PR: #511

This looks like the way to go. There is an open PR with the same approach here: agnivade/wasmbrowsertest#72

Add --no-sandbox

This requires that this PR is first merged to wasmbrowsertest agnivade/wasmbrowsertest#73
Meanwhile, I have created a PR #510 that points to my fork of wasmbrowsertest to confirm that it works.

@mafredri PTAL, this should unblock the failing CI
