Ensure folders have appropriate executable bit set

Noticed when I did a fresh build on a new computer

We require that all folders that we copy into
containers have the executable bit set, so that
they are accessible to users we create like
"tomcat".

There is no good way to do this, so its become a
part of Makefile build process.
