system: Add a 'needed-for-boot?' field to 'mapped-device'.
* gnu/system/file-systems.scm (<mapped-device>)[needed-for-boot?]: New
field.
* gnu/system.scm (operating-system-user-mapped-devices,
operating-system-boot-mapped-devices): Use it instead of trying to
guess. Guessing doesn't work when one refers to a partition using its
label, for instance.
* doc/guix.texi (Mapped Devices): Document 'needed-for-boot?'.
