simplify staged frontend starter scripts (#4341)

* simplify staged frontend starter scripts

Simply invoke the staged x2cpg.sh script without defining additional
JVM properties. If we want to define those by default, it should
rather be done in `src/universal/x2cpg.sh`

N.b. we can't just symlink to the `target/universal/stage/bin/x2cpg.sh`
because of the `SCRIPT_ABS_PATH` handling - we wouldn't be able to
invoke the frontend from different directories any longer.

For now only c2cpg to gather feedback, if it's to your liking I'll
apply the same to all frontends.

* make other frontends setup more similar

there's still some differences, at the same time I'm afraid to break
things downstream...
