don't write a an incorrect rustc version to the fingerprint file
In making https://github.com/holmgr/cargo-sweep/pull/14 I noted that some fingerprint files related to build scripts report being built with a rustc that hashes to "0". To work around this I just marked them as still being needed, even though no rustc that hashes to "0" is currently installed.
I believe that this PR just filles in the correct info for the build script fingerprints. This makes it possible for outside tools to more reliably clean up after cargo, at basically no cost.
@ehuss Thanks again for the help.
