selftests/mm: fix ksft_process_madv.sh test category

ksft_process_madv.sh currently runs run_vmtests.sh with the mmap category.
Update it to run the process_madv category, since ksft_mmap.sh already
runs the mmap category tests.

This avoids running mmap tests twice and ensures that process_madv tests
are run through the kselftest harness.
