02caps: do not create /bin/sh link

caps.sh use !/bin/bash explictly, so no need to ln -sf bash /bin/sh

OTOH, 00dash will create the symlink /bin/sh, 99base will create it if
there's no /bin/sh symlink. It looks bad to creat /bin/sh in other modules.

If a script want to use bash as command interpreter it should use !/bin/bash
or !/bin/sh in case dash is not installed.
