databases/qt4-mysql-plugin & databases/qt5-sqldrivers-mysql: fix build against mysql >= 8.0.1.

From the mysql release notes [1]:

  Incompatible Change: The my_bool type is no longer used in MySQL source code.
  Any third-party code that used this type to represent C boolean variables should
  use the bool or int C type instead.

  Note
    The change from my_bool to bool means that the mysql.h header file now requires
    a C++ or C99 compiler to compile.

  (Bug #25597667)
