clang-view cannot import module ScanView

[Kai Kratz]

Fresh package from today still has the problem of clang-view unable to import module ScanView.

This is the same bug as in: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=838572

Proposed fix does work if applied locally.

Copied from the link:
Hello,

scan-view-3.9 fails to find the needed python modules:

$ scan-view-3.9 scan-build-master/
Traceback (most recent call last):
  File "/usr/bin/scan-view-3.9", line 143, in <module>
    main()
  File "/usr/bin/scan-view-3.9", line 140, in main
    run(port, args, args.root)
  File "/usr/bin/scan-view-3.9", line 70, in run
    import ScanView
ImportError: No module named ScanView

the problem is that os.path.dirname(__file__) is /usr/bin and not
/usr/share/clang/scan-view-3.9/bin
as expected by the script.

A quick way to fix that is to hardcode the scan-view dir:

$ diff -u ../bin/scan-view.old ../bin/scan-view
--- ../bin/scan-view.old 2016-09-22 16:31:01.209052200 +0200

I retested this on 16.04 with clang-3.8 and there exists the same issue.
