Upstream changes:
* Tesseract 4.00.00alpha:
* Version parsing: Ignore suffix (so '4.00.00alpha' == (4, 0, 0))
* Libtesseract: Load libtesseract.so.4 instead of libtesseract.so.3
if available
* Support for Tesseract 3.05.00:
* Builders: Split field 'tess_conf' into 'tess_flags' and 'tess_conf'
* Libtesseract: If available, use
TessBaseAPIDetectOrientationScript() instead of
TessBaseAPIDetectOS
* Libtesseract:
* Workaround: Prevents possible segfault in image_to_string() when
the target language is not available

The tesseract.patch for supporting Tesseract version 3.05.00 has been
applied upstream and we can safely drop it.
We now use substituteInPlace in conjunction with a patch to insert the
relevant store paths instead of sed, so it's less fragile whenever we
have upstream changes in handling of these paths.
I've tested this by reverting 48a941e29f and applying a build
fix patch of Cuneiform 1.1.0 from Arch Linux, because right now
Cuneiform is an experimental version that can't be fixed on behalf of
pyocr (the reason is that pyocr needs to get a list of languages, which
doesn't work in that version anymore).
In addition to that I've successfully built paperwork-backend which by
now is the one package which depends on pyocr. However, I didn't do
runtime tests of Paperwork.

We already have a patch feeling lonely inside the python-modules
directory and to have everything at one place let's actually move pyocr
into its own dedicated directory so it's easier to patch it up (which
we're going to).
Right now, the package fails to build because of a few test failures, so
I haven't tested this apart from evaluating.
