pipe_loop00 passed with this patch.
When we restore a regular fd (not pipe) we do use flags
directly in open() call.

It's because this mask will be restored as rt_sigframe->uc.uc_sigmask.
uc_sigmask will be set as current->blocked in sigreturn, so we should
dump SigBlk in this case.

It has been used at very early stage when
no mincore call was implemented. Not needed

Reduce the pages-xxx.img file size significantly (from 2.1M to ~100K for simple counter test)
by not dumping private file pages, that have not yet changed from its file prototype.
If you'll have problems with it, just let me know and comment the definition of PAGE_ANON not
to block your work.
This uses the implemented earlier flag from mincore.

This entry is for restorer only. In image the fd is -1 always.
