Fix DCAP build in docker (#1306)

* docker: add WORKER_FEATURES_ARG needed for DCAP

* docker: fix LD_LIBRARY_PATH from aesmd service

LD_LIBRARY_PATH must NOT contain the urts library of the aesmd_service, it will override the default one, which will result in a weird SGX enclave initialization errors.

* service/main: follow-up for send_extrinsic signature changes in DCAP only methods

* fixup! docker: fix LD_LIBRARY_PATH from aesmd service
