Subject: [PATCH 1/2] Support more test names in difftest

These all now work. Previously, the path ones did not work:

  - cargo difftest -- difftests::arch::workgroup_memory (original format)
  - cargo difftest -- arch/workgroup_memory (path-like format)
  - cargo difftest -- arch (directory filter)
