Use the current running deno and not `which deno`

[clemens-tolboom]

I want to compile using the current running Deno.

I have a stripped deno which I want to run when doing the Leaf.compile step.

  await runCmd(`cp /usr/local/bin/deno ${tempDir}/bin`);
  await runCmd(`ls -l ${tempDir}/bin/deno`);
  await runCmd(`chmod u+w ${tempDir}/bin/deno`);
  await runCmd(`strip ${tempDir}/bin/deno`);
  await runCmd(`ls -l ${tempDir}/bin/deno`);
