motds: add static motd back and use it as default instead of dynamic …

…motd and add support for custom motd

The dynamic motd has issues with logo word wrap as discussed in 3ec1802 and so can't be used as default. Users who want to use it or a custom one can create a motd file/symlink at `~/.termux/motd.sh` to load a custom motd. To use the dynamic motd provided by termux-tools package, run `ln -sf $PREFIX/etc/motd.sh ~/.termux/motd.sh`

Also check for bash in case its not available before executing motd.
