[PATCH] meson: Fix targetos match for illumos and Solaris.

[PATCH] meson: Fix targetos match for illumos and Solaris.

[Jonathan Perkin]

qemu 8.1.0 breaks on illumos platforms due to _XOPEN_SOURCE and others 
no longer being set correctly, leading to breakage such as:

   https://us-central.manta.mnx.io/pkgsrc/public/reports/trunk/tools/20230908.1404/qemu-8.1.0/build.log

This is a result of meson conversion which incorrectly matches against 
'solaris' instead of 'sunos' for uname.

First time submitting a patch here, hope I did it correctly.  Thanks.

Paolo if you don't mind please replace this link

Commit a988b4c561 from Oct 2022... I'm surprised nobody tried
to build QEMU on illumos for almost 1 year...
