[bug#51838] [PATCH v4 05/45] guix: node-build-system: Add delete-lockfiles phase.

[Philip McGrath]

* guix/build/node-build-system.scm (delete-lockfiles): New function.
Remove 'package-lock.json', 'yarn.lock', and 'npm-shrinkwrap.json',
if they exist.  Because these files specify  both exact dependency
versions and integrity hashes, they only cause problems for Guix.
(%standard-phases): Add 'delete-lockfiles' after 'patch-dependencies'.
