[CRIU] [PATCH 1/3] files: Add file_remap_init

[Cyrill Gorcunov]

Which allows to put this structure into known state
instead of opencoded values. Another reason is that
I think we will have to rework remap engine to address
duplicated ghost directories on image load time instead
of as it will be in next patches.
