Unconditionally ignore system- and global-level gitconfig
We have announced the deprecation of reading the global- and system-level gitconfig originally for %15.0. We had to postpone the deprecation, and now it's scheduled for %16.0.
Distributions have all been converted to set ignore_gitconfig
already. We are thus free to remove the option and only accept Git configuration via [[git.config]]
stanzas.
