sbf-tools assumes write access based on solana cli directory

[TomMD]

cargo build-sbf fails:

[2024-12-07T00:56:35.198892000Z ERROR cargo_build_sbf] Failed to install sbf-tools: Permission denied (os error 13)
cargo build-sbf  16.17s user 2.45s system 45% cpu 41.360 total

Seemingly because the system assumes a good place to place data is global and next to the solana-cli data. This isn't universally true, nix profile install solana-cli will place a solana binary in read-only /nix/store and softlink the binaries. I suggest the build-sbf uses a $HOME/.solana/... directory.
