perf stat: Keep the / modifier separator in fallback
The 'perf stat' fallback for EACCES error sets the exclude_kernel
perf_event_attr and tries perf_event_open() again with it. In addition,
it also changes the name of the event to reflect that change by adding
the 'u' modifier.
But it does not take into account the '/' separator, so the event name
can end up mangled, like: (note the '/:' characters)
$ perf stat -e cpu/cpu-cycles/ kill
...
386,832 cpu/cpu-cycles/:u
Adding the code to check on the '/' separator and set the following
correct event name:
$ perf stat -e cpu/cpu-cycles/ kill
...
388,548 cpu/cpu-cycles/u
