Fix coverity defects: CID 147643, 152204, 49339
CID 147643: Type: String not null terminated
- make sure that the string is null terminated before strlen
and fprintf.
CID 152204: Type: Copy into fixed size buffer
- since strlcpy isn't availabe here, use strncpy and terminate
the string manually.
CID 49339: Type: Buffer not null terminated
- since strlcpy isn't availabe here, terminate the string
manually before fprintf.
