Add a matrix for testing gup based on the current gup_test.  Only run the
matrix when -a is specified because it's a bit slow.

It covers:

  - Different types of huge pages: thp, hugetlb, or no huge page
  - Permissions: Write / Read-only
  - Fast-gup, with/without
  - Types of the GUP: pin / gup / longterm pins
  - Shared / Private memories
  - GUP size: 1 / 512 / random page sizes
