Use different directories when building with meson
Looking to update the Debian/Ubuntu package from 0.36.2 to 0.38.1, some files are installed in different locations when building with autotools or meson
/usr/share/rygel/icons/ (meson) vs /usr/share/icons/ (autotools)
/usr/share/rygel/rygel/presets/ (meson) vs /usr/share/rygel/presets/ (autotools)
Unsure those difference are wanted?
