Configure vfio-user build options with meson setup

ninja < 1.9 uses per-second granularity timestamps to check if build
options are reconfigured by "meson configure". This granularity is not
sufficient if build.ninja is updated fast enough and which results in
ninja not applying reconfigured build options.

To fix this, commit 510f4c13 added 0.5 second
sleep between "meson setup" and "meson configure" but unfortunately it is not
sufficent and build fails sometimes.

Instead of adding sleep this patch proposes to configure build options with
"meson setup".
