[LTP] [PATCH v3 5/6] ima: Rename the folder name for policy files to datafiles

Hi Mimi, Jia,

I wasn't sure about this one as make install isn't that hard to do even during
debugging and policy is more descriptive. But other tests use datafiles as well,
therefore taken as well.

Whole patchset merged, thank you both for your work.

Kind regards,
Petr
