[ptxdist] [PATCH v2] udev: fix error on kernels without uevent helpers

[Clemens Gruber]

Current kernel docs recommend disabling CONFIG_UEVENT_HELPER.

If disabled however, the following error message is shown:
/etc/rc.d/S00udev: line 95: can't create /proc/sys/kernel/hotplug:
nonexistent directory

This patch fixes it by checking if /sys/kernel/uevent_helper exists.

Sorry for the previous mail, I made a mistake in the conditional.
