selftests/bpf: fix unpriv_disabled check in test_verifier

Commit 1d56ade032a49 changed the function get_unpriv_disabled() to
return its results as a bool instead of updating a global variable, but
test_verifier was not updated to keep in line with these changes. Thus
unpriv_disabled is always false in test_verifier and unprivileged tests
are not properly skipped on systems with unprivileged bpf disabled.
