adding recipe for malinka, a C/C++ project configuration package

Hello,

I am opening this request to add a recipe for malinka, a C/C++ project configuration
package of which I am the author.

Link: https://github.com/LefterisJP/malinka

I tested that the package can be properly parsed with `package-info'. Since it's really the first time
I create an emacs package there may be things I have overlooked or misunderstood so if there are any
concerns please share them here and I will address them as soon as possible.

Thanks!
