Krzysztof Struczynski e131e70e21 ima: Set again build_ima_appraise variable

[ Upstream commit b59fda449cf07f2db3be3a67142e6c000f5e8d79 ]

After adding the new add_rule() function in commit c52657d93b05
("ima: refactor ima_init_policy()"), all appraisal flags are added to the
temp_ima_appraise variable. Revert to the previous behavior instead of
removing build_ima_appraise, to benefit from the protection offered by
__ro_after_init.

The mentioned commit introduced a bug, as it makes all the flags
modifiable, while build_ima_appraise flags can be protected with
__ro_after_init.
