tls: fix wrong string variable length overwrite
Some per-domain config string variables (cert_file, ca_file, pkey_file & cipher_list) had their length truncated to that of the corresponding variable in the parent domain. Mostly invisible since the string length was in general ignored (asciiz strings).
