perf evlist: Don't die if sample_{id_all|type} is invalid
Fixes two more cases where the python binding would not load:
. Not finding die(), which it shouldn't anyway, not good to just stop the
world because some particular perf.data file is invalid, just propagate
the error to the caller.
. Not finding perf_sample_size: fix it by moving it from event.c to evsel,
where it belongs, as most cases are moving to operate on an evsel object.o
One of the fixed problems:
[root@emilia ~]# python
>>> import perf
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /home/acme/git/build/perf/python/perf.so: undefined symbol: perf_sample_size
