[libvirt PATCH v3] meson: Improve RPATH handling

Right now we're unconditionally adding RPATH information to the installed binaries and libraries, but that's not always desired. autotools seem to be smart enough to only include that information when targeting a non-standard prefix, so most distro packages don't actually contain it; moreover, both Debian and Fedora have wiki pages encouraging packagers to avoid setting RPATH: https://wiki.debian.org/RpathIssue https://fedoraproject.org/wiki/RPath_Packaging_Draft Implement RPATH logic that Does The Right Thing™ in the most common cases, while still offering users the ability to override the default behavior if they have specific needs.
