[PATCH] ima: rename ima_path_check to ima_file_check

[Mimi Zohar]

ima_path_check actually deals with files!  call it ima_file_check instead.

[PATCH] ima: rename PATH_CHECK to FILE_CHECK

[Mimi Zohar]

With the movement of the ima hooks functions were renamed from *path* to
*file* since they always deal with struct file.  This patch renames some of
the ima internal flags to make them consistent with the rest of the code.
