Fix cc kbc aa param config file parsing

[stevenhorsman]

Sorry, this is my-bad. I blindly copy-pasted the fixes from cdh into AA without paying enough attention and then just testing building it with the offline_fs_kbc and assumed that the workflows would run it for the others. It turns out that it doesn't, so I've tried to correct that and fix the code so that:

~/cc-guest-components/attestation-agent# make KBC=cc_kbc
DEBIANOS is: true
cd app &&  cargo build --release --no-default-features --features "cc_kbc grpc,rust-crypto" --target x86_64-unknown-linux-gnu

works now.

Ah, thanks @stevenhorsman

Can you run cargo fmt on your branch. Seems like one of the checks is complaining about indentation.
