Script replacements doesn't work with jdeb packaging

[kardapoltsev]

I've added a failed tests but I can't figure out whats going wrong.. May be I miss something in configuration? Here is my test https://github.com/kardapoltsev/sbt-native-packager/tree/wip/jdeb-script-replacements/src/sbt-test/debian/jdeb-script-replacements.

$header, $loader_functions are not replaced only $control_functions.

One more... When I've commented out line

 override lazy val projectSettings = inConfig(Debian)(jdebSettings)

test passed.

This is critical. I think the jdeb plugin is missing the filterAndFixPerms call.
We only need the TemplateWriter call to change the placeholders.
