package/mjpg-streamer: bump version

The currently used github repo from oliv3r does not exist anymore.
https://sourceforge.net/projects/mjpg-streamer/ shows that the status of
the original project site is "Inactive" and points to
https://github.com/jacksonliam/mjpg-streamer as the new site.

The new maintainer is active so we bump the package to HEAD of its
master branch which fixes a glibc-related build error:
http://autobuild.buildroot.net/results/4c8/4c8aac898d4580ed0b8b52cef7779d0f6f6a631f/

Further changes due to this bump:
- removed patch 0001, fix was applied upstream:
  https://github.com/jacksonliam/mjpg-streamer/commit/eb4dafd802b366d9b0310e91e7bb93a1082e7657#diff-511ff6908e8db4543e5a59d0ea4a2f1f
- switched to CMake

Added license hash.
