style(install/bundle): make install script dash compatible

We wrote the script that can only be executed on bash.
But Ubuntu sets dash as its default shell environment.
One of the most difference is the POSIX standard echo,
another is parameter of chown can't be put to the end.
So we made some changes to let the script used widely.
And you will not face the syntax error when open this.
