selftests/mm: remove PROT_EXEC req from file-collapse tests

Browse Source 
As of v6.8 commit 7fbb5e1882 ("mm: remove VM_EXEC requirement for THP
eligibility") thp collapse no longer requires file-backed mappings be
created with PROT_EXEC.

Remove the overly-strict dependency from thp collapse tests so we test the
least-strict requirement for success.
