contrib: Clean up outdated parts of gcc-git-customization.sh

Browse source 
It's very unlikely that anybody is still using the old remotes/$user Git
repo setup and still needs this script to be able to migrate it to the
remotes/users/$user structure. Simplify the script by removing those
parts.

This fixes an error that gets displayed in some circumstances:
fatal: no such section: remote.me

contrib/ChangeLog:

	* gcc-git-customization.sh: Delete outdated commands for
	migrating from very old git setups.
