[Buildroot] [git commit] busybox: background udhcpc by default if no lease is obtained

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=2f33654365ffa8fc1b3d8f9e5394a81abb776f66
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The current behavior for busybox' udhcpc is to terminate if no lease is
obtained at start up. Therefore no address is acquired if the link is
established afterwards.

By setting the -b flag udhcpc will background allowing the link to be
established at any time.
