When running on Windows, buildkite can provide backslash-separated paths for the script name, causing the variable substitution here to fail to trim off the basename of the invoked hook file. This changes the hooks to instead use `dirname`, which on these windows systems works with both forward and backward slash separated names.

I integrated this change into a buildkite plugin with a test suite that runs on Linux, macOS and Windows, and it worked on all three operating systems.
