perf scripts python: export-to-postgresql.py: Fix struct.pack() int argument

Browse Source 
Python 3.8 is requiring that arguments being packed as integers are also
integers.  Add int() accordingly.

 Before:

       value = struct.pack("!hiqiiiiii", 4, 8, id, 4, cbr, 4, MHz, 4, percent)
   struct.error: required argument is not an integer

   $ rm -rf perf_data_db-perf-data
