Subject: [PATCH] [IMPROVE] Preload: Generate ignore binaries list

Issue:
Binaries ignored for preloading execution were hardcoded
in modules. This causes errors when binary names are changed.

Solution:
Now ignored binaries pathes are found on manager compile time
and are passed to kernel via debugfs.
