  In order to match the version string, `sed` is used in a couple
cases, and `grep` and `head` in a couple others.

Make the script more consistent and easier to understand by
using the same method, `sed`, for all of them.

This makes the version matching also a bit more strict for
the changed cases, since the strings `rustc ` and `bindgen `
will now be required, which should be fine since `rustc`
complains if one attempts to call it with another program
name, and `bindgen` uses a hardcoded string.

In addition, clarify why one of the existing `sed` commands
does not provide an address like the others.
