device: Treat empty hidraw read as device removal (EOF) (#3174)
* Treat empty hidraw read as device removal (EOF)

When select() reports a hidraw fd as readable but os.read() returns
empty bytes, that's EOF per POSIX — the device has been removed.
Previously this was silently treated as no data, causing the listener
to loop indefinitely on a gone device instead of cleaning up.

* Fix test_ping_errors missing mocks for _read_input_buffer and write

The test was not mocking _read_input_buffer or write, so ping() would
call into real hidapi.read() with a fake handle (fd 1). The empty-read
EOF detection added in the previous commit made this consistently fail
by raising OSError → NoReceiver before reaching the mocked _read path.

Add the same mocks used by the adjacent test_request_errors.
