[Buildroot] [PATCH] utils/getdeveloperlib.py: reduce Cc: list based on package infras

[Yann E. MORIN <yann.morin.1998@free.fr>]

Thomas, All,

On 2021-02-10 09:01 +0100, Thomas Petazzoni spake thusly:
> When a developer has package/pkg-<infra>.mk assigned to him/her in the

>      added line contains a reference to the infra maintained by the

I considered that to be an actual fix, so I applied to master. Thanks.
