Directories in ignore not honoured if not in cwd

[paganwinter]

Folders in the options.ignore list are not ignored if they have a trailing forward slash.

/
├── ignore-first/
|      └── file.txt
└── ignore-second/
        └── file.txt

options.ignore:

['ignore-first/', 'ignore-second']

ignore-first is not ignored in the folders list, while ignore-second is indeed ignored.

dir-glob allows specifying a cwd option as well, which is used by it to determine if an entry in the ignore list is actually a directory or not (https://github.com/kevva/dir-glob/blob/dc6e7978a641fd1e8e4329ba474fb0af65b52519/index.js#L64); this is defaulted to process.cwd(), which doesn't mark such entries as actual directories in the generated glob list.

This can be fixed by passing the original cwd option to dir-glob below: https://github.com/sindresorhus/globby/blob/7807d29e6f4644d32b2602d835b282954cf0db90/index.js#L105
