sdpscanner: fix URL processing
Do not use the fixed-size temporary buffer, instead just parse the
data as a QByteArray.
Grepping through BlueZ sources, I could find only several usages of
SDP_URL_STR{8,16,32}, and all of them suggest that the url is simply
a NULL-terminated string (see [0], [1], [2]).
However, the older BlueZ sources suggest that the url can be not
NULL-terminated as well (see [3]).
To be on a safe side, we provide an implementation that handles both
cases correctly.
