autoconf: fix v2.70 and patching procedure of bin/autom4te.in (#21255)
This PR adds:

1.  A patch that fixes a bug in version 2.70 
    (will be fixed upstream in the next release: https://savannah.gnu.org/support/?110396).
2. A fix for the way we patch shebang in bin/autom4te.in. 

For 2, we need to keep the original modification timestamp of the file. 
Otherwise, we either get an empty man page for autom4te (versions 2.69 and before)
or a failure at the build time (versions 2.70 and after). 

The difference has to do with the update of the missing script: https://git.savannah.gnu.org/cgit/automake.git/commit/lib/missing?id=a22717dffe37f30ef2ad2c355b68c9b3b5e4b8c7

It will take time until developers of Autotools-based packages adjust their scripts 
to the new version, therefore, 2.69 is marked as preferred.
