install: Enable "cryptodisk" handling in GRUB.
This allows 'grub-install' to do the right thing when / or /boot is a LUKS-encrypted partition. Fixes <http://bugs.gnu.org/21843>. * gnu/build/install.scm (install-grub): Add 'setenv' to set 'GRUB_ENABLE_CRYPTODISK'. (wait-for-screen-text): New test. * gnu/tests/base.scm (run-basic-test): Add #:initialization parameter and honor it. * gnu/tests/install.scm (%encrypted-root-os)[kernel-arguments]: Remove. (%encrypted-root-installation-script): Pass '--uuid' to 'cryptsetup luksFormat'. Remove 'sed' invocation. (enter-luks-passphrase): New procedure. (%test-encrypted-os)[value]: Pass #:initialization to 'run-basic-test'.
