perf script: Print "cgroup" field on the same line as "comm"

Commit 3fd7a168bf51 ("perf script: Add 'cgroup' field for output")
added support for printing cgroup path in perf script output.

It was okay if you didn't want any stacks:

    $ sudo perf script --comms jpegtran:23f4bf -F comm,tid,cpu,time,cgroup
    jpegtran:23f4bf 3321915 [013] 404718.587488:  /idle.slice/polish.service
    jpegtran:23f4bf 3321915 [031] 404718.592073:  /idle.slice/polish.service

With stacks it gets messier as cgroup is printed after the stack:

    $ perf script --comms jpegtran:23f4bf -F comm,tid,cpu,time,cgroup,ip,sym
    jpegtran:23f4bf 3321915 [013] 404718.587488:

                55af68e62fff [unknown]
    /idle.slice/polish.service

Let's instead print cgroup on the same line as comm:

    $ perf script --comms jpegtran:23f4bf -F comm,tid,cpu,time,cgroup,ip,sym
    jpegtran:23f4bf 3321915 [013] 404718.587488:  /idle.slice/polish.service
                    5c554 compress_output
                    570d9 jpeg_finish_compress
                    3476e jpegtran_main
                    330ee jpegtran::main
                    326e2 core::ops::function::FnOnce::call_once (inlined)
                    326e2 std::sys_common::backtrace::__rust_begin_short_backtrace

    jpegtran:23f4bf 3321915 [031] 404718.592073:  /idle.slice/polish.service
                    8474d jsimd_encode_mcu_AC_first_prepare_sse2.PADDING
                55af68e62fff [unknown]
