It makes sense that the path would point to /usr/bin because the macros are intended to be used with the RPMs, not random versions of Meson installed from PyPi. Maybe the most sensible thing to do is just admit that we can't reasonably build RPMs for libvirt on platforms where Meson itself is not available as an RPM package. Users can still take the Fedora package and rebuild it on CentOS if they're so inclined, and we should be able to get Meson 0.54.0

included in a future CentOS 8 update to minimize the impact of this problem further, so ultimately we're only losing CentOS 7 coverage for the RPM build in the long-ish run. Note that we're currently not building RPMs as part of the CI pipeline at all :)
