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
