[OE-core] [PATCH 2/2] autoconf-doc: improve reproducibility

[Hongxu Jia]

autoconf-doc package contains autoconf.info.
This file contains date when this file was created, i.e:

     "This manual (31 January 2018) .."

Therefore, two builds done on two different days will show different dates for
otherwise identical files, hence breaking reproducibility.
The date is obtained from mtime of "autoconf.texi", unfortunately we patch this
file and change the mtime as a consequence.
We restore reproducibility by removing the patch modifying "autoconf.texi".
As a consequence certain supplemental information will be not added to the documentation.
In particular:  more details on usage, and on workarounds for non-updated projects.

[YOCTO #12524]

With applying this fix:

    "This manual (24 April 2012) .."
