db_get_table: always append suffix

Commit 2ce60e4 added a check to not
append the suffix for Oracle. This removes this because

- the test was incorrect, and caused non-Oracle installs to never have
  the suffix appended
- with recent changes to Oracle branch, where we specify a short suffix
  in the installer, this is no longer necessary.

The suffix is now systematically appended.
