STM32: fix F410RB vectors size

On F410RB, the size reserved to vectors with ARM toolchains was not properly
defined,which was not the case for other toolchains.

This would cause few tests to fail like EXAMPLE_1 with below error:

HOST: Unknown property: mbed assertation failed: _ptr == (T *)&_data, file: C:/github/mbed/BUILD/mbed/platform/SingletonPtr.h, line 91
