[PATCH v2] xfstests: btrfs, add test for btrfs properties

[Filipe David Borba Manana <fdmanana@gmail.com>]

This test case verifies the btrfs properties feature, a new feature
introduced in the linux kernel version 3.14.

Signed-off-by: Filipe David Borba Manana <fdmanana@gmail.com>

V2: Addressed Dave's comments, removed function to check for existence of
    the btrfs-progs property command and use instead existing function
    _require_btrfs which checks if a btrfs-progs command exists and is
    equivalent to what I had before.
