package/pkg-autotools.mk: LIBTOOL_PATCH_HOOK: also handle libtool 2.5.x

Fixes:
https://autobuild.buildroot.org/results/ac60d29fbcd9fb8ddb21b76b3b185e45e580c006/

Libtool 2.5.x has been released and is starting to be used by upstreams when
generating release tarballs (E.G. openvpn-2.6.14).

https://lists.gnu.org/archive/html/autotools-announce/2024-09/msg00000.html

It needs to be patched similar to earlier versions, and the existing v2.4.4
patch luckily still applies, so extend LIBTOOL_PATCH_HOOK to also patch
2.5.x versions with that.
