pseudo: backport patch to fix xattr performance

In the 1.8 series of pseudo extended attribute handling was reworked
to be a property of inodes, not paths, and as a product fixed extended
attribute semantics on hardlinks. Unfortunately this rework introduced
a slow path around file deletion.

Add a patch for use by the pseudo 1.8.1 recipe which backports a fix
for this regression from the master branch of pseudo.
