Rename boot-parameters to boot-alternatives when appropriate.

Throughout the code base, the token 'boot-parameters' refers to collection of
data that is stored on disk for each system generation. It was confusing to
use it for a list of such records. This comment imposes an alternative name.

* gnu/machine/ssh.scm (machine-boot-parameters): Rename to
  machine->boot-alternatives.
  (machine->boot-alternatives, roll-back-managed-host): Use
  boot-alternatives instead of boot-parameters as appropriate.
* guix/scripts/system.scm (profile-boot-parameters): Rename to
  profile->boot-alternatives.
  (reinstall-bootloader, perform-action): Use boot-alternatives instead
  of boot-parameters as appropriate.
