Switch from libssl_static-host to libssl target

libssl_static-host, when used from this project's
libconscrypt_openjdk_jni target, is no different than libssl. This
switch lets us simplify things and to remove the unnecessary
libssl_static-host target.

Test: Commit has no effect on the contents of
      libconscrypt_openjdk_jni.so, with and without ASAN enabled:
      $ make SANITIZE_HOST=address libconscrypt_openjdk_jni
      $ make libconscrypt_openjdk_jni
