Update README file for Ubuntu local build

- There's an error message using `meson compile -C builddir/` command
```
usage: meson [-h] {setup,configure,dist,install,introspect,init,test,wrap,subprojects,help,rewrite} ...
meson: error: unrecognized arguments: -C builddir/
```

- Update the README.md file for the command  to use
 `ninja` build system with `-C` option.
