uuid: Fix visibility issue for stream operator

This fixes compiler not finding the proper stream operator in some
cases. It seems to be dependent on the order in which stream operators
for different classes are being defined in the compilation unit. Even
defining such operator for one class at the top of the file could break
compilation down bellow in the Uuid printing code that already worked
for a long time, just as if the needed symbol got somehow erased.

An example of such error for the Uuuid instance printed in groups.cc:
  groups.cc:372:21: error: invalid operands to binary expression ('basic_ostream<char, std::char_traits<char>>' and 'const bluetooth::Uuid')
    << ", Uuid: " << group.group_uuid_
    ~~~~~~~~~~~~~ ^  ~~~~~~~~~~~~~~~~~

Moving the operator<<(...) to its 1st argument class namespace fixes
that.
