tiff: version bump to address open CVEs 

- Version bump to 4.0.9, as otherwise ca. a dozen patches would need
  to be added to fix the open CVEs. There have been no API/ABI
  changes between 4.0.6 and 4.0.9, so this is OK.
- Adds patches copied from Debian for CVE-2017-18013 and CVE-2017-9935
  on top.

Subject: [PATCH] * libtiff/tif_getimage.c: fix out-of-bound reads in
TIFFRGBAImage interface in case of unsupported values of
SamplesPerPixel/ExtraSamples for LogLUV / CIELab. Add explicit call to
TIFFRGBAImageOK() in TIFFRGBAImageBegin(). Fix CVE-2015-8665 reported by
limingxing and CVE-2015-8683 reported by zzf of Alibaba.
