tests-mbed_hal-rtc_time: alocate required test data on stack

This is fix for issue 8368.

Test is causing some problems on `REALTEK_RTL8195AM` and `ARM` compiler. There is some kind of memory issue. Probably there is not enough memory space for global data provided by the test. Data definitions have been moved into test function body so, they will land on stack. With this fix the test works on `REALTEK_RTL8195AM/ARM`.
