[Buildroot] [git commit] azure-iot-sdk-c: New package

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=2d837933e55216dc31a2206b063689cfd04a4c01
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Despite newer versions being available, this patch creates a package
for version 2017-05-05, because newer version have issues that need to
be addressed.

Still, the projects install target installs the wrong files, so custom
commands are needed for staging_install and target_install.
