While at it, also remove unnecessary "#!/usr/bin/env python3" in files that only get imported, and adjust other empty/comment lines in the beginnings of the files for consistency. This makes files easier to read, and makes the pmbootstrap codebase more consistent with the build.postmarketos.org codebase.
