initrd: Use non-hyphenated kernel command-line parameter names.

This is to make it less surprising, given the common convention sets forth by
the kernel Linux command-line parameters.

* gnu/build/linux-boot.scm (boot-system): Rename '--load', '--repl', '--root'
and '--system' to 'gnu.load', 'gnu.repl', 'root' and 'gnu.system',
respectively.  Adjust doc.
(find-long-option): Adjust doc.
* gnu/installer/parted.scm (installer-root-partition-path): Adjust accordingly.
* gnu/system.scm (bootable-kernel-arguments): Add a VERSION argument and
update doc.  Use VERSION to conditionally return old style vs new style initrd
arguments.
(%boot-parameters-version): Increment to 1.
(operating-system-boot-parameters): Adjust doc.
(operating-system-boot-parameters-file): Likewise.
* gnu/system/linux-initrd.scm (raw-initrd, base-initrd): Likewise.
* doc/guix.texi: Adjust doc.
* gnu/build/activation.scm (boot-time-system): Adjust accordingly.
* gnu/build/hurd-boot.scm (boot-hurd-system): Likewise.
* gnu/packages/commencement.scm (%final-inputs-riscv64): Adjust comment.
