[PATCH v2 05/13] meson: introduce `libgit_curl` dependency

[Patrick Steinhardt <ps@xxxxxx>]

We've got a set of common source files that we use for those executables
that link against libcurl. The setup is somewhat repetitive though.
Simplify it by declaring a `libgit_curl` dependency that bundles all of
it together.

Note that we don't include curl itself as a dependency. This is because
we already pull it in transitively via the libgit dependency, which is
unfortunate because libgit itself shouldn't actually link against curl
in the first place. This will get fixed in the next commit.
