[PATCH 3/3] perf scripts python: exported-sql-viewer.py: Fix pattern matching with Python 3

[Adrian Hunter <adrian.hunter@intel.com>]

The script allows the user to enter patterns to find symbols.  The pattern
matching characters are converted for use in SQL.  For PostgreSQL the
conversion involves using the Python maketrans() method which is slightly
different in Python 3 compared with Python 2.  Fix to work in Python 3.
