ash: add options to control globbing of hidden files

Add shell options:

- 'nohiddenglob' excludes files with the hidden attribute from
  globbing

- 'nohidsysglob' excludes files with the hidden and system attributes
  from globbing

If both options are enabled 'nohiddenglob' takes precedence.

These options also affect tab completion.

Files that are hidden because they start with a period aren't
affected (unless they also have the hidden attribute).

Costs 160-208 bytes.
