src: remove base64 from process.versions

The `base64` dependency was previously removed along with the update
script (`tools/dep_updaters/update-base64.sh`) but the generated header,
`src/base64_version.h` was left behind and `process.versions` was still
listing the last version of `base64` that was included in Node.js before
it was removed
