build-system: Rewrite using gexps.

* guix/packages.scm (expand-input): Remove 'store', 'system', and
  'cross-system' parameters; add #:native?.  Rewrite to return
  name/gexp-input tuples.
  (bag->derivation): Adjust accordingly.  Lower (bag-build bag).
  (bag->cross-derivation): Ditto.  Instead of #:native-drvs and
  #:target-drvs, pass #:build-inputs, #:host-inputs, and #:target-inputs.
  (%derivation-cache): Remove.
* gnu/packages/bootstrap.scm (raw-build): Turn into a monadic procedure.
* gnu/packages/commencement.scm (glibc-final)[arguments]: Use
  'gexp-input' for the #:allowed-references argument.

  Switch to the use of gexps and 'gexp->derivation'.
  (lower): Remove #:source from 'private-keywords'.

  Likewise.
* guix/build-system/font.scm (font-build): Likewise.
* guix/build-system/gnu.scm (gnu-build): Likewise, and remove
  'canonicalize-reference'.

  (trivial-build): Remove 'store' parameter, change to gexps.
  (trivial-cross-build): Ditto, and change to #:build-inputs & co.
