[lldb] Remove child_process_inherit from the socket classes (#117699)

It's never set to true. Also, using inheritable FDs in a multithreaded
process pretty much guarantees descriptor leaks. It's better to
explicitly pass a specific FD to a specific subprocess, which we already
mostly can do using the ProcessLaunchInfo FileActions.
