cmake: Add shared library as dpdk dependency

librte_eal.a refers to libpthread.so and libdl.so, and libceph-common.so
refers to librte_eal.a. Many test application link libceph-common.so
without linking pthread, it will cause link error.
Such as unittest_interval_set, target_link_libraries (unittest_interval_set
ceph-common)
