Don't attempt installation multiple times
When a dependency of a formula specified on the command-line is also
specified, *after* the dependent formula, installation proceeds as part
of the dependent's dependency tree and then is attempted again because
the user asked for it explicitly. This results in the installer raising
a CannotInstallFormulaError because it has already been installed.
For example:
$ brew install graphviz pkg-config
==> Installing graphviz dependency: pkg-config
...
==> Installing graphviz
...
Error: pkg-config-0.27.1 already installed
We already have a mechanism for dealing with this, but it does not kick
in early enough. Move the installation attempt check into
FormulaInstaller#check_install_sanity and catch the exception in the
appropriate places.
Fixes Homebrew/homebrew#16957.
