uml: make hostfs_setattr() support operations on unlinked open files
This patch allows hostfs_setattr() to work on unlinked open files by calling
set_attr() (the userspace part) with the inode's fd.
Without this, applications that depend on doing attribute changes to unlinked
open files will fail.
It works by using the fd versions instead of the path ones (for example
fchmod() instead of chmod(), fchown() instead of chown()) when an fd is
available.
