Force requested permissions when calling mkdir on VxWorks

Browse Source 
Calling mkdir with mode == 0 works just fine on Linux - it creates a
directory and the permissions are set to 0.
On VxWorks, calling mkdir with mode == 0 uses the default mode set in
the system.
This leads to a failing test (tst_QDir::mkdirWithPermissions(0000)) and
potential confusion when the same code does not behave in the same way
when called on Linux and VxWorks.

To keep the same interface between unix-like systems, explicitly set the
permissions to 0 when on VxWorks.
