Subject: [PATCH] perf evsel: Fix format string in perf_evsel__open_strerror()

From: Namhyung Kim <namhyung.kim@....com>

In case of EPERM or EACCESS, there was a debious "%s" before actual
string so that an user would see "You may not have permission to
collect %sstats." instead of "You may not ... system-wide stats.".
