gnu: bootstrap: 'package-with-bootstrap-guile' uses 'eq?' memoization.

* gnu/packages/bootstrap.scm (package-with-bootstrap-guile): Use
'mlambdaq'.

gnu: commencement: Memoize 'linux-libre-headers-boot0'.

Fixes <https://bugs.gnu.org/30155>.

The effect can be seen in the package graph produced by:

  guix graph -e '(@@ (gnu packages commencement) static-bash-for-glibc)'

This reduces the number of "duplicate" nodes in this graph, i.e.,
distinct package objects that correspond to the same derivation (objects
that are not 'eq?' but semantically equal.)

* gnu/packages/commencement.scm (linux-libre-headers-boot0): Make an
'mlambda' instead of a 'lambda'.
(hurd-core-headers-boot0): Ditto.
