Multiple bugfixes and improvements after building gtk+ from scratch.

- Fix a bug in unzip-extraction.sh that skipped the package that
  requested unzip and instead used the origin template.
- Pass CFLAGS, CXXFLAGS and CPPFLAGS through the environment and unset
  them once the package has been installed.
- Do not show the dependencies required for a pkg more than once time.
