QUUid::createUuid() should not generate identical sequences on UNIX

An unintended side-effect of commit
90a082c9076f35dcca092ade019891e92692710e is that if qrand() is used
without being seeded first, then createUuid() would always generate the
same sequence. This quite likely to happen considering the Qt does not
actually seed the PRNG, but does use it in many places (we do not call
qsrand(), but we do often call qrand()).

Fix this by changing qrand() to calculate a seed, instead of defaulting to
1. This allows us to remove the qsrand() overload with no arguments, since
qrand() will now seed automatically unless manually seeded by the programmer.
