subsys tracing: remove (uintptr_t) casts in snprintk and use %p

Fixes -Werror=format: '%x' expects argument of type 'unsigned int', but
argument N has type 'long unsigned int'

Reproduced with sanitycheck -p bl652_dvk (or -p any other
HAS_SEGGER_RTT) and by adding CONFIG_SEGGER_SYSTEMVIEW=y to
samples/philosophers/prj.conf. sanitycheck adds -Werror.
