Removing myself as uploaders from most science team packages

[Nilesh Patra <nilesh@debian.org>]

Hi,

I am listed as an uploader on a few science team packages. I have lost in interest
in a large majority of them.

Hence, I will be removing myself from uploaders in most of them over time.
I'll probably maintain just a few of them but if you feel like, just take any of them over.

In some of the packages, I am mentioned as the only uploader and hence these are left
without any uploader. I'm thus flagging them via BTS, like I've done in #1119945.
