add perl database support packages

Change in V2:
* Rename recipe to use libdbd-sqlite-perl instead of libdbm-sqlite-perl

In oe-core, only SQLite is supported, so we add perl-DBI and perl-DBD-SQLite.

Test Case:

1) vim local.conf:
...
IMAGE_INSTALL_append = " libdbd-sqlite-perl" PERL_DBM_TEST = "1"
...
2) build core-image-sato and boot the target

3) run "sqlite-perl-test.pl" in target
...

root@qemuarm:~# sqlite-perl-test.pl 
Connect to SQLite's in-memory database
Create table tbl1(name varchar(10), id smallint)
Insert into tbl1 values('yocto',10)
Insert into tbl1 values('windriver', 20)
Select * from tbl1
-----------------------------------
yocto: 10
windriver: 20

Update tbl1 set name = 'oe-core' where id = 10 Delete from tbl1 where id = 20
Select * from tbl1
-----------------------------------
oe-core: 10

Test Success
