Oxide 1.7 makes Unity8 qml tests not pass in a chroot

[Albert Astals Cid]

When using oxide 1.5.5-0ubuntu1 as shipped in vivid the qml tests of unity8 pass just fine.

When using oxide 1.7.8-0ubuntu0.15.04.1 the test for the wizard hangs and says

[0527/073908:FATAL:setuid_sandbox_client.cc(126)] Check failed: IsFileSystemAccessDenied().

The backtrace of the hang is http://paste.ubuntu.com/11386907/

Example of the hang happening in https://jenkins.qa.ubuntu.com/job/unity-phablet-qmluitests-wily/29/console

The test that hangs is test_locationHereTerms, and it tests this QML component: http://bazaar.launchpad.net/~unity-team/unity8/trunk/view/head:/qml/Wizard/Pages/here-terms.qml.

As discussed on IRC, the CHECK failure ([0527/073908:FATAL:setuid_sandbox_client.cc(126)] Check failed: IsFileSystemAccessDenied()) is because the zygote process is able to open the root directory for reading after the suid sandbox has chrooted it to /proc/self/fdinfo, which is owned by root and has 0500 permissions.

The only scenarios under which this check can fail are:

- The actual chroot() really does fail (unlikely)
- The process using Oxide was started by root, meaning that the zygote is able to open its new root directory.

It fails in 1.7 because the check has been made more strict since https://chromium.googlesource.com/chromium/src.git/+/10feab647ef8b96609d087f9936eee9908b057b7%5E!/#F0
