Subject: [PATCH 1/2] Revert "tools: s/strncpy()/strlcpy()/g"
This reverts commit 2ec47d5149e73db97f7877d06d67cb11421097bb.
First, I forgot to actually replace strncpy() with strlcpy(). Second, we don't
want to \0-terminate since this is an abstract unix socket and this is not
required. Instead, let's simply use memcpy() which is more correct and also
silences gcc-8.
