udev-hwdb: fix postinstall scripts failures when multilib enabled

When multilib is enabled and both udev-hwdb and ${MLPREFIX}udev-hwdb are
installed to image, it fails to run one of their postinstall scripts
that they both call ${base_bindir}/udevadm with same user mode qemu.

Duplicate udevadm and add postinst-intercept update_udev_hwdb to fix the
failures.
