lib/string.c: introduce memdup_nul() helper

This is completely analogous to the linux kernel's kmemdup_nul()
helper, apart from the lack of the gfp_t argument: Allocate a buffer
of size {len}+1, copy {len} bytes from the given buffer, and add a
final nul byte.

This pattern exists in a number of places, so this helper can reduce
some boilerplate code.
