[FABN-989] Remove redundant packaging code

Remove the _getChaincodeDeploymentSpec() function and use the Package.fromDirectory() function. Also, async/await Packager.package(), because it looks nicer. Change-Id: Id7471e9ca23861ebe9002b6cb55cf38b6a2cb101 Signed-off-by: Simon Stone <[email protected]>
