[bug#49556] [PATCH v2 2/2] gnu: VDE 2: Update to 2.3.2-0.8599321.

[Leo Famulari]

Updating to this unreleased revision allows us to package VDE 2 with
wolfSSL instead of the obsolete OpenSSL 1.0:

https://github.com/virtualsquare/vde-2/issues/2

* gnu/packages/networking.scm (vde2): Update to 2.3.2-0.8599321.
[source]: Use git-fetch.
[native-inputs]: Add autoconf, automake, and libtool
[inputs]: Replace openssl-1.0 with wolfssl.
[arguments]: Add a 'fix-configure' phase.
