LOG: Revert "[clangd] Enable lit internal shell by default (#170186)"

This reverts commit 671a8ce6bed475830ee9eb67cd3afb950e5a17e1.

This stil broke the clangd-ubuntu-tsan bot. It seems like somehow the
PATH variable is not getting propagated in the
system-include-extractor.test test.

Added: 
    

Modified: 
    clang-tools-extra/clangd/test/lit.cfg.py
    clang-tools-extra/clangd/test/system-include-extractor.test

Removed:
