memif: fix vector overflow when copying strings
When memif sends back socket messages containing strings, we copy
vectors into C-string. Unfortunately, most vectors are not
null-terminated, causing strncpy() read overflow. Moreover, strncpy()
does not null-terminate string in case of max length reached.
This patch introduces helpers to safely copy strings from vectors.
