Remove no longer required dependencies

With the update to rand 0.6.4 we no longer require the dependencies to
rustc_version, semver, and semver-parser. Hence, this change removes
them.

Delete subrepo rustc_version/:rustc_version
Delete subrepo semver/:semver
Delete subrepo semver-parser/:semver-parser

-rustc-version-rs
-==============
-
-A library for querying the version of a `rustc` compiler.
-
-This can be used by build scripts or other tools dealing with Rust sources
-to make decisions based on the version of the compiler.
-
-[![Travis-CI Status](https://travis-ci.org/Kimundi/rustc-version-rs.png?branch=master)](https://travis-ci.org/Kimundi/rustc-version-rs)
-
-# Getting Started
-
-[rustc-version-rs is available on crates.io](https://crates.io/crates/rustc_version).
-It is recommended to look there for the newest released version, as well as links to the newest builds of the docs.
-
-At the point of the last update of this README, the latest published version could be used like this:
-
-Add the following dependency to your Cargo manifest...
-
-```toml
-[build-dependencies]
-rustc_version = "0.2"
-```
-
-...and see the [docs](http://kimundi.github.io/rustc-version-rs/rustc_version/index.html) for how to use it.
-
-# Example
-
-```rust
-// This could be a cargo build script
-
-extern crate rustc_version;
-use rustc_version::{version, version_meta, Channel, Version};
-
-fn main() {
-    // Assert we haven't travelled back in time
-    assert!(version().unwrap().major >= 1);
-
-    // Set cfg flags depending on release channel
-    match version_meta().unwrap().channel {
-        Channel::Stable => {
-            println!("cargo:rustc-cfg=RUSTC_IS_STABLE");
-        }
-        Channel::Beta => {
-            println!("cargo:rustc-cfg=RUSTC_IS_BETA");
-        }
-        Channel::Nightly => {
-            println!("cargo:rustc-cfg=RUSTC_IS_NIGHTLY");
-        }
-        Channel::Dev => {
-            println!("cargo:rustc-cfg=RUSTC_IS_DEV");
-        }
-    }
-
-    // Check for a minimum version
-    if version().unwrap() >= Version::parse("1.4.0").unwrap() {
-        println!("cargo:rustc-cfg=compiler_has_important_bugfix");
-    }
-}
