ci: install curl and json-c for LGTM
ci: install curl and json-c for LGTM

Since upstream commit 6da95b04b4f22284d5b40cc03fa19e6dc514339f, tpm2-tss
needs curl and json-c to build. These are not picked up automatically by
LGTM because we build tpm2-tss manually in after_prepare, so add them to
the packages to install.
