crate_id should specify different filename

[lilyball]

The crate_id right now is "github.com/sfackler/rust-openssl". This means the resulting filename is librust-openssl-4fdb0f34-0.0.dylib. This also means that in order to reference this crate, you need to say something like

extern mod openssl = "rust-openssl";

because rust-openssl is not a valid identifier.

I would recommend that the library name be changed to just "openssl", but modifying the crate_id to

#[crate_id="github.com/sfackler/rust-openssl#openssl:0.0"];

You may also want to pick a non-0.0 version number as well.

I was holding off on this until rust-lang/rust#11086 goes through since it'll make it unbuildable with rustpkg.

The crate should use the name openssl now.
