db: Upgrade to 6.0.35

The SRC_URI was changed to point gentoo distfiles because now Oracle
request authorization for download the source code [1], there are no changes
in the LICENSE since version 6.0.20 when the LICENSE changes to AGPL-3
[2], also the md5sum was review to be sure that is the same.

This minor upgrade fix an issue related to multiple rpm instances querying
the database [3].

The bugfixes related are,

- Fixed a bug that may lead to a crash when opening multiple environments
in a multi-threaded program.
- Fixed a bug where closing a panic environment raised access violation
  and crashed the program.

For see the complete list of changes mostly bugfixes between 6.0.30 and 6.0.35 [4].
