bst is choking because of the redirect

Latest tarball include meson files now

Latest tag supports meson but the tarball doesn't include meson
files :/

This completes 078ceca5

Latest tag supports meson but the tarball doesn't include meson
files :/

Current master is meson only, and the latest tarball doesn't
support meson

RIP WebKitPluginProcessGtk2

Part of #199

The new cargo plugin renders the old cargo mechanics
obsolete, this commit removes:

 o plugins/crate.py: The old crate downloading Source plugin

 o utils/generate_cargo_dependencies.py: The script to manually
   update crate using bst files

Instead of using the crate plugin which requires manual
invocations of utils/generate_cargo_dependencies.py.

As we are building from a tarball

master drops autotools but no tarball with meson exist yet

- don't build platform and sdk on i686 (dropped by freedesktop-sdk)
- build platform compat extensions on 32 bit only
- don't build sdk compat on x86_64

Fixes #168

Current master doesn't build, see
amtk#1
