[PATCH v2 2/4] perf script: fix symbol insertion behavior in db-export

[Chris Phlipot <cphlipot0@gmail.com>]

Use the dso__insert_symbol function instead of symbols__insert in order to
properly update the dso symbol cache.

If the cache is not updated, then duplicate symbols can be unintentionally
created, inserted, and exported.

This change prevents duplicate symbols from being exported due to
dso__find_symbol using a stale symbol cache.
