[package] add library 'libbsd'

This library contains core functionality usually (but obviously not always)
provided by libc implementations which isneeded by OpenWrt core packages.
For instance the functions 'strlcat', 'strlcpy' are not implemented in
eglibc but needed by hotplug2 (udevtrigger)

+ This library provides useful functions commonly found on BSD systems, and lacking on others like GNU systems, thus making it easier to port projects with strong BSD origins, without needing to embed the same code over and over again on each project.
