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

[ Upstream commit 17e548405a81665fd14cee960db7d093d1396400 ]

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.
