utils: Define 'target-hurd?' predicate.

It behaves similarily to the other target-...? procedures.
The usage of hurd-triplet? / target-hurd? in libgc appears
incorrect to me, as (%current-system) is normally never false.

* gnu/packages/hurd.scm (hurd-triplet?): Move to ...
* guix/util.scm (target-hurd?): ... here, let its argument
  default to (%current-target-system) or (%current-system),
  and write a docstring.
* gnu/packages/hurd.scm
  (hurd-target?, hurd-system?): Use target-hurd? instead of
  hurd-triplet?.
* gnu/packages/bdw-gc.scm (libgc): Likewise.
* gnu/packages/cross-base.scm
  (cross-libc)[arguments]<#:configure-flags>: Likewise.
  (cross-libc)[arguments]<#:phases>: Likewise.
  (cross-libc)[arguments]<#:native-inputs>: Likewise.
* gnu/packages/make-boostrap.scm
  (%glibc-stripped)[inputs]: Likewise.
