Get core dump code to work

------------------------------------------------------
Subject: Get core dump code to work
From: Petr Vandrovec <petr@xxxxxxxxxxxxxx>
File based core dump code was broken by pipe changes - relative llseek
returns absolute file position on success, not relative one, so dump_seek()
always failed when invoked with non-zero current position.
Only success/failure can be tested with relative lseek, we have to trust
kernel that on success we've got right file offset. With this fix in place
