  Changed paths:
    M compiler-rt/test/lit.common.cfg.py

  Log Message:
  -----------
  Only add `darwin_log_cmd` lit shell test feature when the log can be queried.

Summary:
Follow up fix to 445b810fbd4. The `log show` command only works for
privileged users so run a quick test of the command during lit config to
see if the command works and only add the `darwin_log_cmd` feature if
this is the case.

Unfortunately this means the `asan/TestCases/Darwin/duplicate_os_log_reports.cpp`
test and any other tests in the future that use this feature won't run
for unprivileged users which is likely the case in CI.
