debian: build debug symbol package

Before this patch all debug symbols were stripped off and simply
discarded.  GDB without debug symbols is barely usable, but at
the same time distributing binaries with debug symbols would
drastically increase strongswan/libstrongswan package size.

Instead of discarding debug symbols, it would be better to strip
them off into a dedicated debian package.  So that, if needed, one
could still install them and use GDB.
