Bug#953922: gfal2: Build-Depends on unused libattr1-dev

[Guillem Jover]

Source: gfal2
Source-Version: 2.17.2-1
Severity: minor

Hi!

This package used to use libattr for its xattr support, but got
switched to use the native support from glibc, but the Build-Depends
got left behind.

Thanks,
Guillem
