[Buildroot] [PATCHv2] package/eudev: tweak initscript

[Gustavo Zacarias]

Make the udev initscript trigger in a coherent way, i.e. first set
subsystems, then device and then let the whole thing settle.
Otherwise for usb_modeswitch udev rules they never kick in since the
storage aspect (device) gets claimed first and the switch ignored.
Also set the settle timeout to a smaller value than the default
120 seconds to avoid stalling too much.
