206a1d2b - Revert "Reapply "[compiler-rt] Default to Lit's Internal Shell""

Revert "Reapply "[compiler-rt] Default to Lit's Internal Shell"" This reverts commit 225341343f4db6c068c6e4b6848f243dbc1da7b0. This caused a bunch of buildbot failures: 1. https://lab.llvm.org/buildbot/#/builders/17/builds/12328 - fixed-shadow.c uses parantheses, almost seems flaky. 2. https://lab.llvm.org/buildbot/#/builders/186/builds/13651 - log-path_test.cpp is unresolved on some builders. 3. https://lab.llvm.org/buildbot/#/builders/64/builds/6289 - unset is not found 4. https://lab.llvm.org/buildbot/#/builders/42/builds/6809 - ulimit issues 5. https://lab.llvm.org/buildbot/#/builders/169/builds/16628 - flaky JIT failures that are now a lot more frequent.
