Use newer Javy and omit source code from wasm

Javy v1.2.0 is a couple of years old. The current version is v7.0.1.

Besides being newer it also builds smaller WASM files (1/10 in size).

Version 7.0.1 also has feature for omitting the JS source from the
WASM file. When used it produces even smaller WASM files.

```console
$ ./javy-x86_64-linux-v1.2.0 compile out.js -o plugin-1.2.0.wasm
$ ./javy-x86_64-linux-v7.0.1 build out.js -o plugin-7.0.1.wasm
$ ./javy-x86_64-linux-v7.0.1 build out.js --codegen source=omitted -o plugin-7.0.1-omit-source.wasm
$ ls -lh *.wasm

```
