fix -Werror build: logging.c: always use literal with snprintf

A recent commit added an snprintf that passes a pointer to a literal directly
to snprintf. Since passing pointers to printf formats is a vulnerability in
case user supplied data may be passed in the format, modern compilers warn
against that, which breaks our -Werror builds. Even though this is just a
pointer to a literal, it needs to be an actual literal to make compilers happy.

Use printf("%s", c) instead of printf(c).

Note that our current build slave's gcc does not enforce that yet, while newer
compilers do.

  logging.c:338:4: warning: format not a string literal and no format arguments [-Wformat-security]
       ret = snprintf(buf + offset, rem, c_subsys);
