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

git is delegating webacces for URLs using TLS to libcurl.
However our native libcurl build does not find a ca-certificate.crt
unless its curl-native work dir still exists and thus git will
fail.
If a recipe uses AUTOREV with a git repo using https as its protocol
parsing of that recipe will fail fetching the latest HEAD.

Fix that by depending on ca-certificate and give its location
to libcurl via git's envrironment variable GIT_SSL_CAINFO.
