Revert [support] GlobPattern: add support for `\` and `[!...]`, and allow `]` in more places

This reverts r375051 (git commit a409afaad64ce83ea44cc30ee5f96b6e613a6e98)

The patch does not work on Windows due to `\` in filenames being interpreted as escaping rather than literal path separators when used by lld linker scripts.
