description:
sim: fix issues with pwrite(); don't enable fstatfs
this patch fixes issues with changeset 11593
use the host's pwrite() syscall for pwrite64Func(),
as opposed to pwrite64(), because pwrite64() does
not work well on all distros.
undo the enabling of fstatfs, as we will add this
in a separate pate.
