Stop specifying version for vmlinux dependency

The vmlinux crate isn't really versioned as such, as the only
compatibility guarantee provided is that git history won't be clobbered.
There is also no intention of publishing it.
As such, there is no point in specifying a version -- the SHA1 pinning
the git commit is sufficient. Remove any version specifications.
