[PATCH] fix problems with dev.d and udevstart

Here is the correction for the dev.d/ scripts too. We should pass
the right argv[0] here too. A script may depend on the right value, as
udev does with udev/udevstart.

Here is the old version:
  [pid  4692] execve("/etc/dev.d/default/log.dev", ["./udev", "block"], [/* 41 vars */]) = 0

this the new one:
  [pid  9832] execve("/etc/dev.d/default/log.dev", ["/etc/dev.d/default/log.dev", "block"], [/* 41 vars */]) = 0
