selftests/mm: fix a verbose log in run_test

JIRA: https://issues.redhat.com/browse/RHEL-130531

The line does not exist in the original upstream commit, and is obviosusly
a verbose print, such as below:

    TAP version 13
    running: ./virtual_address_range
    # -------------------------------
    # running ./virtual_address_range
    # -------------------------------
    # TAP version 13
    # 1..1
    # ok 1 # SKIP prctl(PR_SET_VMA_ANON_NAME) not supported
    # # 1 skipped test(s) detected. Consider enabling relevant config options to improve coverage.
    # # Totals: pass:0 fail:0 xfail:0 xpass:0 skip:1 error:0
    # [PASS]
    ok 1 virtual_address_range

Upstream Status: RHEL-Only
Fixes: 8546332 ("selftests/vm: enable running select groups of tests")
