trace: make CTF metadata prettier

This is simply a cosmetic change.

Before:
event {
    id = 17;
    name = "lib.eal.alarm.set";
    fields := struct {
        uint64_t us;uintptr_t cb_fn;uintptr_t cb_arg;int32_t rc;
    };
};

After:
event {
    id = 17;
    name = "lib.eal.alarm.set";
    fields := struct {
        uint64_t us;
        uintptr_t cb_fn;
        uintptr_t cb_arg;
        int32_t rc;
    };
};
