[sheepdog] [PATCH v1] unittest: fix coredump bug for unit-test

[Robin Dong]

From: Robin Dong <sanbai at taobao.com>

Test case in test_hash.c will call create_vdisks() which need to
check sys->cinfo.flags, but variable 'sys' is uninitialized in
unit-test environment. Therefore we need to init 'sys' before
calling create_vdisks().
