Add package wget and perl modules.

Add package wget and perl modules.

LSB needs wget to download packages but wget provided by busybox doesn't
support some options such as '-N'.

LSB perl test 4.1.6-2 case all/tst_perlModPresent.pl,
../lib/Class/ISA/t/00_about_verbose and ../lib/Class/ISA/t/01_old_junk.t
fail because of lack of these modules, add them to make test pass.

File CORE/config.h which is provided by perl-dev and file
unicore/version which is provided by perl-doc are required by LSB perl
test cases.

Add perl-dev and perl-doc to packagegroups-core-lsb.
