meson: Allow custom prefixes for third-party packages

labwc, magpie, gsd does not always share the same prefix as
budgie-desktop and sometimes they are just installed in some
unusual paths. For example, in NixOS labwc is installed in
/nix/store/xxx-labwc-0.8.2/bin, and in Arch Linux gsd-media-keys
is installed in /usr/lib/. Simply don't hardcode these paths.
