[bug report] xfsdump fails to build against xfsprogs 5.18.0

[corinhoad@gmail.com]

Hello,

I package xfsdump for NixOS, and I have found that a recent upgrade from 
xfsprogs 5.16.0 to 5.18.0 has caused a build failure for xfsprogs. See 
[1] for an excerpt from the build logs. My novice investigation of the 
issue and disccusion IRC indicates that the removal of DMAPI support is 
behind this.

Best,
Corin Hoad
