libmount: introduce LIBMOUNT_FORCE_MOUNT2={always,never,auto}

[karelzak]

Let's introduce a stable workaround for use cases where new kernel API is not ready to use.

The patch does not use "goto enosys" to exit as nothing in the hookset is initialized yet.

Addresses: #1992
Addresses: #2283

I am not setup for proper isolated build;
please upload stand-alone v 2.39-8 artifacts as was done previously for v 2.39-6: *.pkg.tar.zst
