(stable) Just fatal for any setting of open_basedir

Browse source 
Summary:
Fixes T11627.

Beyond being complex, I have no real reason to believe these checks even work (and they don't test repositories, file storage, logfiles, etc).

Test Plan:
Faked the error:

{F1813433}

// may need to access in the filesystem; and use of this option seems

// 'open_basedir' restricts which files we're allowed to access with
// file operations. This might be okay -- we don't need to write to
// arbitrary places in the filesystem -- but we need to access certain
// resources. This setting is unlikely to be providing any real measure
// of security so warn even if things look OK.
