perf tools: Add basic event modifier sanity check
Updating event parser to allow any non zero string containing [ukhpGH]
characters for event modifier.
The modifier sanity is checked later in parse-event object logic. The
check validates modifier to contain only one instance of any modifier
(apart from 'p') present.
v2:
- added length check suggested Namhyung Kim
