[PATCH] vim: fix redact_pass.vim for macOS

Problem: redact_pass.vim did not work on macOS machines
Fix: add resolve($TMPDIR) to the autcmd pattern list


pass creates files under /private/var/<some-stuff> on macOS.
redact_pass.vim uses the following pattern to detect when to
enable the plugin:


This pattern expands to "/var/<some-stuff>//pass.?*/?*.txt"
on my macbook and has two problems:

1. The double forward slash in the expanded pattern (after <some-stuff>)
2. pass uses /private/var but the pattern looks for /var

Turns out, /var on macos is just a symlink to /private/var.
The autocmd fails to trigger because it is trying to match
the pattern: "/var/<some-stuff>//pass.?*/?*.txt"
to filename: "/private/var/<some-stuff>/pass.<random-chars>/<random-chars>.txt"

The simplest fix is to make $TMPDIR point to "/private/var/..."
which is achieved by calling resolve on $TMPDIR prior to running
the autocmd. This also handles the double forward-slash.
