[KYUUBI #1368] Turn off debugging in dist scripts

### _Why are the changes needed?_
`set -x` is currently used in dist scripts for debugging and the console looks a bit messy, it seems better to turn it off and users can enable it themselves if necessary.

### _How was this patch tested?_
- [ ] Add some test cases that check the changes thoroughly including negative and positive cases if possible

- [ ] Add screenshots for manual tests if appropriate

- [x] [Run test](https://kyuubi.readthedocs.io/en/latest/develop_tools/testing.html#running-tests) locally before make a pull request

Closes #1368 from murong00/branch-1366.
