Inject MANIFEST.MF also for source jar files

[jerboaa]

For Quarkus productization source jars are expected to have META-INF/MANIFEST.MF files in them. Inject them when they're not already there like we do for the actual jar artefact.

Diff ignoring whitespace looks like this:

I've tested this locally with --maven-deploy-local.

Before this patch (no manifests in source jars):

$ for i in word collections nativeimage; do echo "----------------------- $i ------------------------"; echo $i.jar=$(jar -tf mandrel-build/lib/jvmci/$i.jar | grep MANIFEST); echo $i.src.zip=$(jar -tf mandrel-build/lib/jvmci/$i.src.zip | grep MANIFEST); done
----------------------- word ------------------------
word.jar=META-INF/MANIFEST.MF
word.src.zip=
----------------------- collections ------------------------
collections.jar=META-INF/MANIFEST.MF
collections.src.zip=
----------------------- nativeimage ------------------------
nativeimage.jar=META-INF/MANIFEST.MF
nativeimage.src.zip=

After this patch (manifests in both, the regular jars and the source jar):

$ for i in word collections nativeimage; do echo "----------------------- $i ------------------------"; echo $i.jar=$(jar -tf mandrel-build/lib/jvmci/$i.jar | grep MANIFEST); echo $i.src.zip=$(jar -tf mandrel-build/lib/jvmci/$i.src.zip | grep MANIFEST); done
----------------------- word ------------------------

Merging as this is needed for a release coming up.

Thanks for taking care of this @jerboaa

Diff ignoring whitespace looks like this:

FYI you can get this diff on github by appending the URL with ?w=1 or by clicking the gear box in the "Files Changed" tab of the PR and ticking "Hide whitespace"

OK. Thanks for the tip!
