  [lldb] Fix broken pipe error (#127100)

During LLDB testing on slow machines with the remote-linux platform all
tests from llgs category fail with python exception `BrokenPipeError`.
The main reason of these failures is slow start of lldb-server in
gdbserver mode. Due to this desired gdbserver socket does not have time
to open by the time the Python script tries to establish a connection.

List of failed tests:

```
TestAppleSimulatorOSType.py
TestGdbRemoteAttach.py
TestGdbRemoteAuxvSupport.py
TestGdbRemoteCompletion.py
TestGdbRemoteExitCode.py
TestGdbRemoteExpeditedRegisters.py

TestGdbRemoteKill.py
TestGdbRemoteLaunch.py
TestGdbRemoteModuleInfo.py
TestGdbRemotePlatformFile.py

TestGdbRemoteGPacket.py
TestGdbRemoteTargetXmlPacket.py
TestGdbRemote_QPassSignals.py
TestGdbRemoteThreadName.py

```

This patch implements an additional check for the opened socket on
lldb-server side and fixes this error.
