  [lldb][test] Assume clang supports -gmodules (#201333)

We currently spend 50ms in most dotest invocations to check if clang
supports `-gmodules`. The expensive part of this check is creating the
clang process to run `clang --help`.

`-gmodules` was added 11 years ago and is present in any compiler that
has even a remote chance in supporting the rest of our test suite. This
patch just assumes that our compiler supports -gmodules if it is clang.
