Fix Python exception in gdb pretty-printer basegfx

Add single quotes around the namespace::class construct, when calling
gdb.parse_and_eval(), otherwise this exception is thrown:
"Python Exception <class 'gdb.error'> A syntax error in expression, near `)xxx)->count($'.:"
The reason is a possible conflict with '::' referring a static variable
(https://sourceware.org/gdb/onlinedocs/gdb/Variables.html).

Also improved the B2DPolyPolygonPrinter::children method to avoid a
segmentation fault, when accessing member m_value.
