[PATCH 4/5] btrfs-progs: misc-tests: Make test cases work or skipped on 64K page size system

[Qu Wenruo <wqu@suse.com>]

[BUG]
The following test cases fails on aarch64 64K page size mode:
      [TEST/misc]   010-convert-delete-ext2-subvol
  failed: mount -t btrfs -o loop /home/adam/btrfs-progs/tests//test.img /home/adam/btrfs-progs/tests//mnt
  test failed for case 010-convert-delete-ext2-subvol
  make: *** [Makefile:387: test-misc] Error 1

[CAUSE]
Most of them are caused by the lack of subpage sized sector size
support.
Or the conflicts sector size (64K) and nodesize (smaller than 64K).

[FIX]
Check if the current kernel accepts subpage sized sector size and
manually specify 4K sector size.
