Add quick and dirty script to help updating aosp-mirror.conf

The aosp-mirror files grew a lot. And updating it by hand start being

as it could help people make big updates to the aosp-mirror.conf file.

I used this script and method for the
3951e3d417cbb2432570e2d9eafcbf2ee64a8365 commit (Add Replicant 11
redirects).
