meson: allow optional static linking of shared code in udev helpers
This makes the helper binaries significantly bigger (in some cases, the final
size depends on link options and optimization level), and is only useful for
distributions which want to provide the option to install udev without systemd.
As the linking is improved, the difference between the columns might shrink,
but it's unlikely that linking libshared statically could ever be more
efficient.
E.g. with -O0, no -flto:
(static) (shared)
src/udev/ata_id 999176 85696
src/udev/cdrom_id 1024344 111656
src/udev/collect 990344 81280
src/udev/scsi_id 1023592 115656
src/udev/v4l_id 811736 17744
When linked dynamically, install_rpath must be specified, so add that.
