Older kernels don't have /sys/fs/btrfs. btrfs/010 will happily run
until it goes to check its work against sysfs and finds those files
don't exist. This patch introduces a require check to ensure that
the sysfs files are present before running.

This is a regression test for patch "Btrfs: fix delalloc accounting
leak caused by u32 overflow". It creates a bunch of delalloc extents
and merges them together to make sure the accounting is done right.

Since snapshot aware defrag has been disabled in kernel, and we all
have learned to ignore the failure of btrfs/010, lets just remove
it.
