config: plug user_config leak
We generate filenames for the user_config ("~/.gitconfig")
and the xdg config ("$XDG_CONFIG_HOME/git/config") and then
decide which to use by looking at the filesystem. But after
selecting one, the unused string is just leaked.
This is a tiny leak, but it creates noise in leak-checker
output.
