Check sanitizer status for TCL tests in CI

[PragmaTwice]

Previously, TCL tests did not sense sanitizier errors when executed, and we fixed that in this PR.

Generally looks good.

I'd like to ask whether this is a regression that we check them previously or we didn't.

I'd prefer to echo output in the if block.

Is it like if [[ $SANITIZER_OUTPUT ]]; then echo $SANITIZER_OUTPUT; exit 1; fi ?

Seems there are some ASan errors in TCL tests: https://github.com/apache/incubator-kvrocks/runs/7125505577?check_suite_focus=true

Weird since sometime these errors do not appear.

Thanks everyone, the ASan report has been addressed in #699, and I will try to solve it later. Merging...
