ci: add unit test to github action

[machinly]

Add unit tests to Github Action, and comment out some test files that can't pass.

The code review of this patch is as follows:

• A cleanup function is added to remove log, db and dbsync directories
• Functions are defined to check if tcl is installed, setup build directory, and pika binary and configuration file
• The removal of the "rm -rf ./db" command from the original script may potentially leave residual database files in the current directory and the new cleanup function does not remove these either.
• Code seems to lack proper error handling mechanisms, i.e., it just exits with an error message but does not specify what caused the error or how to fix it.
• It might be useful to add a logging mechanism to stream output to a separate file and ensure that users can review test results more easily.

Some possible improvements to the existing code may include:

• Adding proper error handling to the code, such as specifying error types and potential solutions.
• Instead of using multiple functions, it would be better to use a single function broken down into logical blocks for readability and simplicity.
• Checking the permissions before removing files or directories to avoid accidental deletion of critical files that can cause issues later on.
• Clearing the necessary directories more effectively by using more specialized commands like find instead of rm -rf.
