Revert "git: git-replacement-native: depend on ca-certificate"

This reverts commit 2e99ffda70fd95b5eab3de47048032349cd66f4b.

git-replacement-native is used only to provide a newer version than may
be installed on the system; apart from that, it should work more or less
the same.

In particular, it is using the host system's /etc/gitconfig; it should
also use the system CA certificates, otherwise it will break HTTPS
connections in environments that need local certificates, for example
for a corporate HTTP proxy. The override had been added to deal with
curl-native relying on the existence of its workdir to access CA
certificates, which has been fixed in the curl recipe now.
