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.

+8ef17919509e ("hurd: Fix EINVAL error on linking to a slash-trailing path
+[BZ #32569]) made symlink return ENOTDIR, but the gnulib testsuite does
+not recognize it for such a situation, and EEXIST is indeed more
