[thud][PATCH 8/9] Revert "nettle: fix ptest failure"

[Armin Kuster <akuster808@gmail.com>]

From: Richard Purdie <richard.purdie@linuxfoundation.org>

This reverts commit 83faaf7b2a5f4fc4ae504b300134409e90389770.

This should never have merged as the change was rejected upstream and adding a library
to the ptest package resulted in it providing that SONAME which led to being
included in images like core-image-sato.

This in turn led to a ton of ptest failures in the 2.7 r1 QA report.
