Subject: file-systems: Support forced checks & repairs.

* gnu/build/file-systems.scm (check-ext2-file-system)
(check-bcachefs-file-system, check-btrfs-file-system)
(check-fat-file-system, check-jfs-file-system, check-f2fs-file-system)
(check-ntfs-file-system, check-file-system): Take and honour new FORCE?
and REPAIR arguments.  Update the docstring.  Adjust all callers.
* gnu/system/file-systems.scm <file-system>: Add new SKIP-CHECK-IF-CLEAN?
and REPAIR fields.
(file-system->spec, spec->file-system): Adjust accordingly.
* gnu/build/linux-boot.scm (mount-root-file-system): Take new
SKIP-CHECK-IF-CLEAN? and REPAIR keyword arguments.  Thread them through
to CHECK-FILE-SYSTEM.
* doc/guix.texi (File Systems): Document both new <file-system> options.
