file-systems: 'file-system-needed-for-boot?' always returns #t for "/".
Reported by Nikita Karetnikov.

* gnu/system/file-systems.scm (<file-system>): Rename 'needed-for-boot?'
  accessor to '%file-system-needed-for-boot?'.
  (file-system-needed-for-boot?): New inlinable procedure.
* gnu/system.scm (other-file-system-services)[file-systems]: Rely on
  'file-system-needed-for-boot?' to handle the "/" case.
  (operating-system-initrd-file)[boot-file-systems]: Likewise.
