mute lint warns when running run-manager via cargo

[dsocolobsky]

When running/compiling run-manager via cargo we see a lot of annoying warnings of the type

warning: unexpected `cfg` condition value: `custom-heap`
  --> architectures/decentralized/solana-treasurer/programs/solana-treasurer/src/lib.rs:29:1
   |
29 | #[program]
   | ^^^^^^^^^^
   |
   = note: expected values for `feature` are: `anchor-debug`, `cpi`, `default`, `idl-build`, `no-entrypoint`, `no-idl`, and `no-log-ix-name`
   = note: using a cfg inside a macro will use the cfgs from the destination crate and not the ones from the defining crate
   = help: try referring to `$crate::custom_heap_default` crate for guidance on how handle this unexpected cfg
   = help: the macro `$crate::custom_heap_default` may come from an old version of the `solana_program_entrypoint` crate, try updating your dependency with `cargo update -p solana_program_entrypoint`
   = note: see <https://doc.rust-lang.org/nightly/rustc/check-cfg/cargo-specifics.html> for more information about checking conditional configuration
   = note: `#[warn(unexpected_cfgs)]` on by default
   = note: this warning originates in the macro `$crate::custom_heap_default` which comes from the expansion of the attribute macro `program` (in Nightly builds, run with -Z macro-backtrace for more info)

afaik this is an Anchor thing and we can just ignore them
