Bump git2 to 0.20.3

This updates the git2 crate to 0.20.3, with only one change to increase
the requirement of libgit2-sys to 0.18.3 to force an update to libgit2
1.9.2. This is only done as a caution to ensure that packages that are
only checking direct-dependency versions will pick up the update.
