xfstests: support post-udev device mapper nodes

Browse Source 
Because of udevs complaining device mapper now creates /dev/dm-N as the real
device nodes, and just symlinks the /dev/mapper/ names to it.  This would be
easy if everything used the /dev/mapper clear names, but most system utilities
translate them back to the /dev/mapper/ names and thus confuse various test
cases.  Add support to _is_block_dev to read symlinks, and add documentation
on how to run xfstests on device mapper volumes.

To use xfstests on device mapper always use the /dev/mapper/<name> symlinks,
not the /dev/dm-* devices, or the symlinks created by LVM.
For example:
TEST_DEV=/dev/mapper/test
SCRATCH_DEV=/dev/mapper/scratch
