gnu: glibc/hurd: Add patches for the 64bit Hurd.

These patches fix:

  * Statically linked tar to hang/segfault upon issuing the "--mtime=@1"
  warning; this is also applicable for the 32bit Hurd using glibc-2.39!

See <https://lists.gnu.org/archive/html/bug-hurd/2024-11/msg00115.html>.

  * Shell replacement problems for the 64bit Hurd.

See <https://lists.debian.org/debian-hurd/2024/07/msg00063.html>.

  * Findutil's gnulib-tests/test-sigaction failure.

* gnu/packages/patches/glibc-hurd-pthread_setcancelstate.patch,
gnu/packages/patches/glibc-hurd64-fault.patch,
gnu/packages/patches/glibc-hurd64-intr-msg-clobber.patch,
gnu/packages/patches/glibc-hurd64-sgms-context.patch: New file.
* gnu/local.mk (dist_patch_DATA): Register them.
* gnu/packages/base.scm (glibc/hurd): Use them.

+Upstream-status: Taken from <https://salsa.debian.org/glibc-team/glibc/-/blob/25a0a47767fe7dc5151eb36afaade17218728efe/debian/patches/hurd-i386/local-static_pthread_setcancelstate.diff>.
+
+This is needed for the 64bit Hurd statically linked tar non to hang when
+issuing a warning.
+
+since the move of libpthread functions to libc, glibc dropped the use
+of __libc_ptf_call. But htl hasn't made the move yet, so we have to use
+__libc_ptf_call there for now.
