[Buildroot] [PATCH v2] libgudev: New package

[Nathaniel Roach <nroach44@gmail.com>]

As libgudev recently was split from the main systemd/udev source,
	this library is now required to build NetworkManager.

This library is only relevant to systemd, as the code it contains
	is still contained in eudev.

Add the package; add it as a dependency to NetworkManager; and
	tweak systemd's Config.in message accordingly.

---
Changes v1 -> v2
(Changes as suggested by Peter Korsgaard)
 - Added the toolchain dependencies
 - Dropped NM references in package
 - Added _LICENSE_FILEs
 - Conditionally depend on libgudev in NM if using systemd
