...only for manual key management

Also, change the default Knot error (for errnos not in the mapping table) from
KNOT_ERROR (-1000) to a new value KNOT_ERRNO_ERROR (-500). The aim is to distinguish
between DNS logic errors and the underlying OS (syscall and library) errors.

The primary problem is that zs_set_input_file() always returns ZS_FILE_OPEN
for open() error, so it's impossible to distinguish between file name
and permission errors for example.
