Add grub_util_disable_fd_syncs call to turn grub_util_fd_sync calls into no-ops, and use it in programs that copy files but do not need to take special care to sync writes (grub-mknetdir, grub-rescue, grub-mkstandalone). On my laptop, this reduces partmap_test's runtime from 1236 seconds to 204 seconds.
