lib: cmsis_rtos_v2: changed printformat that produced warnings

Changed the print format for unsigned 32-bit variables that produced
warnings when compiled with newlib instead of the standard C library.
Chose to replace %d with PRIu32 because the latter is more portable
and adapts to the types of the standard C libraries.
Tested with and without newlib, and with sanitycheck.
