selftests/livepatch: Replace set_dynamic_debug() with setup_config() …

…in README

Commit 35c9e74 ("selftests/livepatch: Make dynamic debug setup and
restore generic") introduced setup_config() to set up the environment
for each test. It superseded set_dynamic_debug().  README still mentions
set_dynamic_debug(), so update it to setup_config() which should be used
now in every test.
