Fix resolver test failure caused by mismatching between libcrypto and

libssl

In order to solve the coverage testing problem, aosp/1625082 moved
the dependency of resolv_{unit,gold}_test from libcrypto to
libcrypto_static.
However, in some testing combinations, the system libssl doesn't
match with the libcrypto_static.
To fix the problem, also statically link libssl for those tests.
