Fix/build without root

[AndASM]

We don't need sudo or root privileges to create files belonging to root in a .tar. Requiring sudo to build can cause compatibility issues, extra difficulty building, and security risks. This branch modifies distrod_packer to pack the opt_distrod.tar.gz as a normal user.

Makefile has also been updated to print a basic help message when make is run. This shows as either make or make help. This was added to increase discoverability for new users, novices, and other potential contributors.

Further updates and cleanup of distrod_packer could be done following this change. Such as removing obsolete functions such as make_dir_deletable. This cleanup has not been done.
