perf beauty msg_flags: Add missing %s lost when adding prefix suppression logic
When the prefix suppresion/enabling logic was added, I forgot to add an
extra %, which ended up chopping off the strings:
Before:
# perf trace -e *mmsg --map-dump syscalls
[299] = 1,
[307] = 1,
DNS Res~ver #3/14587 sendmmsg(106<socket:[3462393]>, 0x7f252b0fcaf0, 2, MSG_) = 2
chronyd/1053 recvmmsg(4, 0x558542ca5740, 4, MSG_, NULL) = 1
DNS Res~ver #2/14445 sendmmsg(106<socket:[3461475]>, 0x7f252ab09af0, 2, MSG_) = 2
DNS Res~ver #2/14444 sendmmsg(146<socket:[3457863]>, 0x7f2521a7aaf0, 2, MSG_) = 2
DNS Res~ver #2/14445 sendmmsg(106<socket:[3461475]>, 0x7f252ab09af0, 2, MSG_) = 2
