font-util installs encoding maps into /usr/share/fonts/X11. This path
may not exist on the host (many distros install these into
/usr/share/fonts/util) so they must exist in the sysroot in order for
e.g. `pkg-config --variable=mapdir fontutil` to work correctly. However,
currently /usr/share/fonts is explicitly not installed into sysroots, so
the encoding maps were not getting found.
Fix this by explicitly staging ${datadir}/fonts/ into the sysroot.
