All Python files in the LLVM repository were reformatted with Black [1].
Files inside the LLDB subproject were reformatted in 2238dcc39358. This
patch updates a handful of tests that were added or modified since then
and weren't formatted with Black.

This reverts commit 3254623d73fb7252385817d8057640c9d5d5ffd1.
One test has been updated to add the "-s" flag which along with
86fd957af981f146a306831608d7ad2de65b9560 should fix the tests on MacOS.
An assert on hijack listener added in that patch was removed, it seems
to be correct on MacOS but not on Linux.
This fixes#62068.
After 8d1de7b34af46a089eb5433c700419ad9b2923ee the following issue appeared:
```
$ ./bin/lldb /tmp/test.o
(lldb) target create "/tmp/test.o"
Current executable set to '/tmp/test.o' (aarch64).
(lldb) platform process launch -s
error: Cannot launch '': Nothing to launch
```
Previously would call target->GetRunArguments when there were no extra
arguments, so we could find out what target.run-args might be.
Once that change started relying on the first arg being the exe,
the fact that that call clears the existing argument list caused the bug.
Instead, have it set a local arg list and append that to the existing
one. Which in this case will just contain the exe name.
Since there's no existing tests for this command I've added a new file
that covers enough to check this issue.
