[bug#65479] [PATCH core-updates 06/61] gnu: docbook: Remove leftovers.

[Bruno Victal]

docbook-xsl patches are probably remnants from
1f7d94597f1e78776f854eeca46c03a3aded8466.

* gnu/packages/docbook.scm: Remove unused import.
* gnu/packages/patches/docbook-xsl-nonrecursive-string-subst.patch: Remove.
* gnu/packages/patches/docbook-xsl-support-old-url.patch: Ditto.
* gnu/local.mk: Unregister it.
* gnu/packages/moreutils.scm (moreutils)[native-inputs]: Drop obsolete
comment.
