tizen -dev images: remove development files
The images are more useful for debugging the images themselves (openssh,
serial console enabled, debug information installed) than they are for
developing apps.
The advantage of disabling the development files are faster build
times and less distractions at runtime: installing development files
often also pulls in additional, unwanted packages (for example,
avsystem-devel pulls in avsystem, which fails to start properly
and is not needed).
