lsbsetup: drop it

lsbsetup: drop it

lsbsetup provides script LSB_Setup.sh to setup LSB test on image. But
script LSB_Test.sh provided by lsbtest replaces its function now. So
drop lsbsetup.

lsbsetup links /etc/localtime to HongKong zoneinfo file to make LSB
wcsftime test case pass(Yocto 1079). But the test case PASS without
this link, so remove the link.

Other 2 links are moved to packages lsb.

[Yocto 3278]
