Trusty: Add BoringSSL modulewrapper for ACVP

In order to validate the BoringSSL implementation in Trusty using ACVP,
we need a modulewrapper tool that forwards requests to Trusty and back
to the ACVP tool. Adds this tool, which interfaces with the Trusty ACVP
testing service.

Test: make trusty_acvp_modulewrapper
Test: adb shell "acvptool -wrapper trusty_acvp_modulewrapper -json vectors/ACVP-AES-CBC"
