perf trace: Show comm/tid for augmented_syscalls
To get us a bit more like the sys_enter + sys_exit combo:
# perf trace -e tools/perf/examples/bpf/augmented_syscalls.c,openat cat /etc/passwd > /dev/null
0.000 ( ): openat(dfd: CWD, filename: 0x31b6dda8, flags: CLOEXEC)
0.009 ( 0.009 ms): cat/3619 openat(dfd: CWD, filename: 0x31b6dda8, flags: CLOEXEC) = 3
0.051 ( ): openat(dfd: CWD, filename: 0x31d75ce0, flags: CLOEXEC)
0.054 ( 0.010 ms): cat/3619 openat(dfd: CWD, filename: 0x31d75ce0, flags: CLOEXEC) = 3
0.539 ( ): openat(dfd: CWD, filename: 0xca71506b)
0.543 ( 0.115 ms): cat/3619 openat(dfd: CWD, filename: 0xca71506b) = 3
#
After:
# perf trace -e tools/perf/examples/bpf/augmented_syscalls.c,openat cat /etc/passwd > /dev/null
0.000 ( ): cat/4919 openat(dfd: CWD, filename: 0xc8358da8, flags: CLOEXEC)
0.007 ( 0.005 ms): cat/4919 openat(dfd: CWD, filename: 0xc8358da8, flags: CLOEXEC) = 3
0.032 ( ): cat/4919 openat(dfd: CWD, filename: 0xc8560ce0, flags: CLOEXEC)
0.033 ( 0.006 ms): cat/4919 openat(dfd: CWD, filename: 0xc8560ce0, flags: CLOEXEC) = 3
0.301 ( ): cat/4919 openat(dfd: CWD, filename: 0x91fa306b)
0.304 ( 0.004 ms): cat/4919 openat(dfd: CWD, filename: 0x91fa306b) = 3
