[lttng-dev] [PATCH lttng-tools 06/13] Misleading error handling: utils_create_pid_file() should return 0 on success

[Mathieu Desnoyers]

fprintf returns a positive value on success, which is used as return
value for utils_create_pid_file(), which is odd. This is in preparation
for main() refactoring.
