Unit tests and Integration tests do not clean up temporary files

[eval-exec]

Bug Report

When make test and make integration finished, there are many temporary dirs created by ckb exists in TMPDIR.

Current Behavior

Expected Behavior

I expect temporary files created by unit tests and integration tests should be cleaned up.

Environment

• CKB version: latest develop branch
• Chain: /
• Operating system: NixOS 23.11
• Arch: x64
• Installation: Built from source

Additional context/Screenshots

This bug can reproduced by these steps:

mkdir /tmp/ckb_integration_test
export TMPDIR=/tmp/ckb_integration_test
make integration
# ...
# after make integration finish.  there are many temporary files created by integration test exists
❯ ls /tmp/ckb_integration_test/

And unit test have same issue:

mkdir /tmp/ckb_unit_test
export TMPDIR=/tmp/ckb_unit_test
make test
# ...
# after make test finish.  there are many temporary files created by integration test exists
❯ ls /tmp/ckb_unit_test/
