gnu: glibc/hurd: Fix gnulib tests.

With glibc-2.41 several gnulib tests are failing on the Hurd in multiple core packages
- test-once1
- test-pthread_sigmask1
- test-symlink/test-symlinkat

This adds the relevant patches from glibc upstream or the version from the
debian glibc adapted for glibc 2.41.

* gnu/packages/patches/glibc-hurd-2.41-pthread-once.patch: New patch.
* gnu/packages/patches/glibc-hurd-2.41-pthread-sigmask.patch: New patch.
* gnu/packages/patches/glibc-hurd-2.41-symlink.patch: New patch.
* gnu/packages/base.scm (glibc/hurd): Add them.
* gnu/local.mk : Register them.

+This is glibc ccdb68e829a31e4cda8339ea0d2dc3e51fb81ba5 adapted for glibc 2.41
+
+Note: compared to upstream, this was changed to exposing pthread_once as version
+2.41.
