linux emulation package updates

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

I've just committed many new packages for Linux emulation on NetBSD
using libraries from OpenSUSE 15.5. The selection was based on getting
an equivalent of suse131_gtk3 to install and report no missing
libraries using 'ldd' (from suse151_binutils) on the lib64/*so files.

The packages provide x86_64 binaries only (no 32-bit libraries) since
I have no use case for that.

Please test them by setting

SUSE_PREFER=  15.5

in your /etc/mk.conf.

The plan is to make this the default version on NetBSD/amd64, but I'd
like some feedback from others first.

I'd also like to clear out the old versions: suse100_* and suse121_*
at least. Comments on that?

Cheers,
 Thomas
