[SPARK-3126][SPARK-3127][SQL] Fixed HiveThriftServer2Suite

This PR fixes two issues:

1. Fixes wrongly quoted command line option in `HiveThriftServer2Suite` that makes test cases hang until timeout.
1. Asks `dev/run-test` to run Spark SQL tests when `bin/spark-sql` and/or `sbin/start-thriftserver.sh` are modified.

Author: Cheng Lian <lian.cs.zju@gmail.com>

Closes apache#2036 from liancheng/fix-thriftserver-test and squashes the following commits:
