Fix missing tools in apex genrules

Pass all the tools used by apexer to the genrules that run apexer
so that they will all be copied into the sandbox.

Also remove the host_required on libconscrypt_openjdk_jni, it won't
do anything once tool sandboxing is enabled.  Fix it instead by
using jni_libs on signapk to depend on libconscrypt_openjdk_jni.
