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 5956876 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 directly execute motd.sd and rely on interpreter instead of executing with bash in case its not available or user does not want a bash script as motd.sh
