[lldb][test] Prevent TestqOffsets.py picking up host binaries (#157432)
Due to a fallback in GDBRemoteCommunicationClient.cpp, on Linux we will
assume a PID of 1 if the remote does not respond in some way that tells
us the real PID.
So if PID 1 happened to be a process that the current user could read,
we would try to debug that instead. On my current machine, PID 1 was
sshd run by root so we would ignore it. If I changed the fallback to
some process ID run by my user, the test would fail.
To prevent this, select the remote-linux platform before creating the
target. This means we won't attempt any host lookups.
Fixes #155895
