meson: bump minimal openssl/libcrypto to 3.0.0

meson: bump minimal openssl/libcrypto to 3.0.0

OpenSSL 3.0 introduces semantic versioning, thus one can reason about
the supported (and/or broken) API/ABI by glancing at the number.

Version 3.0 was released in late 2021 and is adopted by, at least:
 - CentOS Stream 9
 - Debian 11 aka oldoldstable
 - Fedora 38
 - openSUSE Leap 15.5
 - Ubuntu 22.04

This means that some older, yet maintained, enterprise-y linuxes will be
left in the dark. Namely:
 - RHEL 6,7
 - SLES 11,12,15?
 - Ubuntu {14,16,18,20}.04

To the best of my knowledge, all of them are in deep maintenance mode
and do not target latest kmod releases.

Bumping the requirement, allows us to focus on a single DSO and its API,
as we move to dlopen(libcrypto.so) with the next commit(s).
