[BUG] sim/segger: stream_rtt.c fails at lib_puts_t int vs long unsigned int

[lupyuen]

Description / Steps to reproduce the issue

Reported by nuttx-dashboard.org: segger/stream_rtt.c fails to build due to incompatible types in lib_puts_t. segger/stream_rtt.c has not been changed recently. Has the Segger API changed?
