fix: Have util/mkerr.pl comply better with our coding style

fix: Have util/mkerr.pl comply better with our coding style

util/mkerr.pl produced lines like these:

    {ERR_PACK(ERR_LIB_EVP, 0, EVP_R_OPERATION_NOT_SUPPORTED_FOR_THIS_KEYTYPE),
    "operation not supported for this keytype"},

According to our coding style, they should look like this:

    {ERR_PACK(ERR_LIB_EVP, 0, EVP_R_OPERATION_NOT_SUPPORTED_FOR_THIS_KEYTYPE),
     "operation not supported for this keytype"},

This nit was correctly picked up by util/check-format.pl
