Fix crash on Ubuntu 24.04 ARM64 (FreeRTOS#1253)

On Ubuntu 24.04 ARM64, PTHREAD_STACK_MIN is 0x20000 which does not fit
in unsigned short, size of which is 2 bytes. Casting PTHREAD_STACK_MIN
to unsigned short in FreeRTOSConfig.h results in
configMINIMAL_STACK_SIZE getting defined to 0 which leads to SIGSEV.

This change removes the not needed casting of PTHREAD_STACK_MIN to
unsigned short.
