Subject: cmd/info: prevent duplicate dependency display.

Before:

    $ brew info llvm
    ==> Dependencies
    Build: xz ✔, xz ✔, xz ✔, xz ✔, xz ✔, xz ✔

    $ brew info --json=v1 llvm
    ... "dependencies":["xz","xz","xz","xz","xz","xz"], ...

After

    $ brew info llvm
    ==> Dependencies
    Build: xz ✔

    $ brew info --json=v1 llvm
    ... "dependencies":["xz"], ...

Closes Homebrew/homebrew#36653.
