dev-perl/BerkeleyDB: Bump to version 0.630.0

dev-perl/BerkeleyDB: Bump to version 0.630.0

This is a very long awaited bump because the last few times I tried,
     I hit serious problems and punted it till later. This time I
     finally dug into the problem and worked out why it exploded in
     tests....

- EAPI7
- Improve DB configuration to properly work on Gentoo ( how 0.550.0
  works and passes tests anywhere may be a slight mystery )
- Remove empty variable assignments
- Remove useless tests and strip unused files from install image

Upstream:
- Updates for BDB 6.2 and 6.3
- expose set_lg_filemode
- Fix build breakage with DBD 5.2 to 6.2
- sync dbinfo from DB_File
- Add missing dTHX declaration in my_db_strerror
- Fix missing txn code in db_remove
- Add __heap_exist prototype for db 5.2+
