Subject: [PATCH] audit: flag incorrect automake/autoconf/libtool dep handling

Just makes the audit cough out this:
```
 * :libtool is deprecated. Usage should be "libtool"
 * :autoconf is deprecated. Usage should be "autoconf"
 * :automake is deprecated. Usage should be "automake"
```

Closes Homebrew/homebrew#39303.
Closes Homebrew/homebrew#39322.
