[PATCH v1 2/6] perf time-utils: Fix 32-bit nsec parsing

[Ian Rogers <irogers@google.com>]

The "time utils" test fails in 32-bit builds:
```
...
parse_nsec_time("18446744073.709551615")
Failed. ptime 4294967295709551615 expected 18446744073709551615
...
```

Switch strtoul to strtoull as an unsigned long in 32-bit build isn't
64-bits.

Fixes: c284d669a20d ("perf tools: Move parse_nsec_time to time-utils.c")
