Add QIODevice::canReadLine call to QBluetoothSocket
At least on Linux the QIODevice parent class reads and buffers a
large chunk of data when readLine() is called. This call effectively
empties the private linear data buffer, and subsequent canReadLine()
calls to the private buffer returns false. This is problematic if
the data contained several lines of data; the
QBluetoothSocket::canReadLine() returns false but readLine() returns
valid lines of data.
This commit adds a parent class call so that it's buffers are also
taken into account as per QIODevice documentation.
Fixes: QTBUG-101690
