motds: fix and update dynamic motd.sh

- The logo added in new dynamic motd would break due to word wrap if terminal columns were less than max line length. This fixes the issue by not drawing a logo if terminal columns are too few at draw time. Note that logo will still break if terminal size is changed after drawing.

- Use TERMUX_APP_PACKAGE_MANAGER instead of TERMUX_MAIN_PACKAGE_FORMAT

- Add donate link instead of gitter which should already exist in community link, including matrix rooms link.
