perf script: Add missing separator for "-F ip,brstack" (and brstackoff)
Prior to commit 55b9b50811ca ("perf script: Support -F brstack,dso and
brstacksym,dso"), we were printing a space before the brstack data. It
seems that this space was important. Without it, parsing is difficult.
Very sorry for the mistake.
Notice here how the "ip" and "brstack" run together:
$ perf script -F ip,brstack | head -n 1

After this diff, sanity is restored:
$ perf script -F ip,brstack | head -n 1
22e18c4 0x22e19e2/0x22e190b/P/-/-/0 0x22e19a1/0x22e19d0/P/-/-/0 0x22e195d/0x22e1990/P/-/-/0 0x22e18e9/0x22e1943/P/-/-/0 0x22e1a69/0x22e18c0/P/-/-/0 0x22e19f7/0x22e1a20/P/-/-/0 0x22e1910/0x22e19ee/P/-/-/0 0x22e19e2/0x22e190b/P/-/-/0 0x22e19a1/0x22e19d0/P/-/-/0 0x22e195d/0x22e1990/P/-/-/0 0x22e18e9/0x22e1943/P/-/-/0 0x22e1a69/0x22e18c0/P/-/-/0 0x22e19f7/0x22e1a20/P/-/-/0 0x22e1910/0x22e19ee/P/-/-/0 0x22e19e2/0x22e190b/P/-/-/0 0x22e19a1/0x22e19d0/P/-/-/0
