Usual approach for LTP is to quit test early on missing prerequisites
(e.g. disabled SELinux in ima_selinux.sh). This is even more important
for IMA tests run with LTP_IMA_LOAD_POLICY=1, where it's useful to avoid
loading policy if test will be skipped with TCONF (often requires reboot).

Therefore first check $REQUIRED_BUILTIN_POLICY (value of ima_policy
kernel cmdline parameter, it can TCONF), then run the test specific
setup and finally run the policy if needed.

Changes from v1:
* Instead of explicitly state that test setup should be run before
loading policy just postpone loading policy after running test setup.
