package/graphite2: security bump to version 1.3.14

- Switch site to github, here is an extract of
  https://sourceforge.net/projects/silgraphite:
  "This project has been deprecated. Graphite2, a new version of the
  Graphite engine, is available at: https://github.com/silnrsi/graphite
  with its own bug tracker."
- graphite2 can be built statically since version 1.3.11 and
  https://github.com/silnrsi/graphite/commit/2f143c04da5caa43ddf4dba437b2f2bc26bf4238
- Update indentation in hash file (two spaces)

Extract from ChangeLog:

1.3.14
    . Bug fixes
    . Allow features to be hidden (for aliases)
    . Move to python3
    . Rename doc files from .txt to .asc

1.3.13
    . Resolve minor spacing issue in rtl non-overlap kerning
    . python3 for graphite.py
    . Better fuzzing
    . Better building on windows

1.3.12
    . Graphite no longer does dumb rendering for fonts with no smarts
    . Segment caching code removed. Anything attempting to use the segment cache gets given a regular face instead
    . Add libfuzzer support
    . Builds now require C++11
    . Improvements to Windows 64 bit builds
    . Support different versions of python including 32 bit and python 3
    . Various minor bug fixes

1.3.11
    . Fixes due to security review
    . Minor collision avoidance fixes
    . Fix LZ4 decompressor against high compression

The fixes due to security review are a little bit vague, a quick search
on github seems to indicate that those issues could be related to
segcache which has been removed since version 1.3.12:
