[bug#53238] [PATCH] gnu: tree: Remove stddata feature.

[Olivier Dion]

* gnu/packages/admin.scm (tree)
[arguments]: Add 'remove-stddata-feature phase after 'unpack phase.

Since version 2.0.0, there's a new feature call `stddata`.

>From the ChangeLog:
--------------------------------------------------------------------------------
Output un-indented JSON on file descriptor 3 ("stddata") automatically if file
descriptor 3 is present (currently Linux only.) Maybe switch to BSON.
--------------------------------------------------------------------------------

This feature breaks some UNIX utilities.  Fix it by disabling the feature.
