meson: fix compilation with at least spice

This commit should also get rid of pointless option warnings.

Also removed an extra ) that was causing a bad cpu value.

+Subject: [PATCH] coredata: Check for built-in options as host options
+
+These options often don't exist for the build machine, as they're
+generally invalid (ie, prefix, libdir, etc). So we should always check
+for their existance as host optiuons, since all we want to know in this
+case is if the option is yeilding (valid per-subproject), and build/vs
+host doesn't matter in that cases:
+
+Fixes #8613
