perf trace: Fixup etcsnoop example
[ Upstream commit 1d59cb1bbd4cbe5a8f8032242cdacea5658129cf ]
Where we don't have "raw_syscalls:sys_enter", so we need to look for a
"*syscalls:sys_enter*" to initialize the offsets for the
__augmented_syscalls__ evsel, which is the case with etcsnoop, that was
segfaulting, fixed:
# trace -e /home/acme/git/perf/tools/perf/examples/bpf/etcsnoop.c
