use strlcpy & strlcat (#74)
* refactor checkpubkeyperms() with safe BSD functions
fix gcc8 warnings
```
svr-authpubkey.c: In function 'checkpubkeyperms':
svr-authpubkey.c:427:2: warning: 'strncat' specified bound 5 equals source length [-Wstringop-overflow=]
strncat(filename, "/.ssh", 5); /* strlen("/.ssh") == 5 */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
svr-authpubkey.c:433:2: warning: 'strncat' specified bound 16 equals source length [-Wstringop-overflow=]
strncat(filename, "/authorized_keys", 16);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
