This means:
 - It’s always available, so the tests no longer have to be optional
 - It gets bundled in release tarballs so the above is always true
 - The `meson setup` and `meson build` commands will automatically
   update it if needed
 - It gets built using meson, rather than autotools, so the old
   GNU make build system in xdgmime can be dropped (see
   xdgmime#36

)
 - The `xdgmime-path` meson option is no longer needed and has been
   dropped
