[inputs]: Add comment justifying use of older libxml2-2.11.
* gnu/packages/patches/perl-xml-libxslt-fix-configure.patch: Delete file.

-Subject: [PATCH] Avoid C implicit function declaration in Makefile.PL (C99
- compat)
-
-Future compilers are likely not to support implicit function
-declarations.  Add a fake prototype so that the probes will
-not always fail with such compilers.
