build: replace multimatch dependency with glob ignore option

The `multimatch` package was only used in the saucelabs test bundling
script to filter out spec files that should be ignored during saucelabs
testing. This functionality can be replaced with `fast-glob` package's
`ignore` option. This removes the need for the `multimatch` package within
the repository.
