meson: Make sed optional

petere · petere · commit 9aa374dcfb76 · 2023-12-21T10:10:05.000+01:00
sed is used only if dtrace or selinux are enabled. Those options are only used on Unix platforms, which should have sed. But we don't want to make sed a hard requirement on Windows, which was the case in meson until now. This just changes sed to be not-required by meson. If you happen to use a system with, say, dtrace but without sed, you might get a slightly complicated error from meson during the build, but that seems better than making the requiredness a complicated conditional that will need to be maintained.
